AutoCAD does not start: possible reasons, deletion of problem files, fatal errors and problem solving. Troubleshooting AutoCAD Launch Problems Autocad Does Not Launch After Installation

In this article, we will look at the most common license errors that can occur when using Autocad CAD.

So, we are considering a situation when you use a licensed version of Autocad, according to our observations, it is with such versions, oddly enough, that the largest number of errors occurs. At the same time, if you use illegal versions, there are no problems with the license (but there are problems with the law), again, oddly enough, it would seem it should be the other way around)))

The most common error that occurs (often occurs when using temporary licenses) is characterized by such symptoms - Autocad starts, tries to check the license, then the following window is displayed:

When you click to try again, nothing happens, and if you click Finish, the program starts, but then a window appears with the inscription The license is invalid. Contact an Authorized AutoCAD Dealer and the program is closed.

Ways to solve the problem:

0.If you have a licensed Autocad, the easiest way is to contact the seller immediately and find out everything from him, because you paid a lot of money. But if this is not possible, try the following tips.

1.If you have a temporary license (for example, an annual one), make sure that in your personal account on the website www.autodesk.com you have allowed access to licenses for all devices, because by default immediately after purchasing a license or after renewal, when a new one is issued, access is not allowed.

2. Delete license information, it is stored in the FLEXNet folder, which is located on the system drive in the ProgramData folder (this folder is hidden by default) if you have Windows 7 and newer or in Documents and Settings \\ All Users \\ Aplication Data \\ FLEXNet / if you have Windows XP. This folder also contains information about other programs that use the FLEXnet system to check the license, so watch out for unnecessary ones. After uninstallation at startup Autocad will ask for re-activation (serial number needed) and will work normally again.

3. If you have Autocad 2014 or Autocad 2015 and a temporary license, a situation may arise when you deleted the folder, but no re-activation occurs and the program still cannot connect to the license server. In this case, the hotfix released by Autodesk specifically to solve this situation will help, you can download it from here. After installation, everything should work and the license will be checked correctly.

4. If all these methods did not help, try rearranging the entire program, with the obligatory cleaning of traces in the ProgramData folders and in Appdata in the user profile.

The information was obtained in the process of solving similar problems with licensed versions of software from our customers, we hope it will be useful.

Attention! We DO NOT install / activate and other illegal activities with unlicensed software versions !! For your information, the use of activators is Article 273 of the Criminal Code of the Russian Federation, the punishment for individuals is from 2 to 4 years in prison.

Also, for information, an annual subscription to Autocad LT (two-dimensional design) costs 20 thousand / year, in our opinion this is a lifting cost for an organization. Also, there is a free replacement (albeit, like all free ones, which works worse than the analogue), this is the Russian software Nanocad.

Now AutoCAD is the most popular drawing software in the world. Dozens of users install it on their computers every day. However, not everyone can immediately switch to interacting with this software. Sometimes there are problems with starting AutoCAD, which is associated with various factors. Next, we want to demonstrate the known methods for solving this problem, which have been tested for operability.

There are a number of reasons why startup problems may appear. All of them are solved in different ways, so the user needs to find a suitable method for him by enumerating options. However, the task will be greatly simplified if the user knows the error code or he has familiarized himself with the notification that appears on the screen, if it is, of course, present.

Startup Error Code Detector

When installing AutoCAD, the user receives a large number of additional utilities on his computer, which will be useful when interacting with the software. This includes a tool that allows you to track the behavior of the program and identify existing problems. You can use it like this:

If the error is known for the utility being used, then it will definitely be indicated in the file. Based on this, it is already necessary to select the optimal solution. We suggest that you familiarize yourself with the following methods to find a suitable option. When the file is empty, just start looking for a fix by running each option presented in sequence.

Method 1: Configure User Account Control Settings

The Windows operating system has a built-in tool that allows you to control all the changes you make. It also acts as a security mechanism to prevent any files from being changed without the administrator's knowledge. AutoCAD developers also talk about conflicts with this tool, recommending to disable it if suddenly there are any problems with the software performance. This is what we will do now.

1. Discover "Start" and go to "Control Panel".



2. Select a category in it "Security and Service Center".



3. Navigate through the menu on the left to the menu "Changing User Account Control Settings".



4. Slide the switch to state "Never notify".



5. Confirm the changes by clicking on "OK".

In doing so, make sure that all actions are performed under the administrator account. If it is not, please log in with this profile. Read more about this in our other material by clicking on the link below.

Method 2: Deleting the Cascadeinfo.cas file

As you know, in AutoCAD, licensing is checked over the Internet. Responsible for this is the document called "Cascadeinfo.cas"... It can be damaged due to unexpected PC shutdown or some other activity. This leads to problems with launching the software, as even the developers themselves claim. This problem is solved by the banal deletion of this document (the next time the application is launched, it will be successfully restored).

Method 3: Delete the contents of the FLEXnet folder and check the service

FLEXnet is another product-related tool from Autodesk. It also performs the function of checking the license when starting the software. If the license check failed, a corresponding notification will appear on the screen, indicating that you need to clear the contents of the directory and check the licensing service, which happens like this:

Method 4: Clean up the Temp folder

Windows system folder named "Temp" stores temporary files that are accumulated throughout the entire period of using the PC. Over time, the contents of this directory can take up a large amount of hard disk space. Because of this, AutoCAD sometimes simply refuses to launch. To correct this situation, a banal folder cleaning will allow. This can be done both independently and with the help of software. You will find more detailed information on this topic in our other material by clicking on the link below.

Method 5: Install additional system libraries

If, when you try to start AutoCAD, you receive a notification about the absence of any DLL file, this means that additional libraries were not installed, in which these objects are present. Usually the elements of the DLL format store certain parameters and the software periodically accesses them, therefore the stability of the application depends on them. We advise you to download the latest version, all Vusial C ++ and .NET Framework assemblies to accurately resolve the issue of missing DLLs. It will come in handy when working with other software. You will find all the necessary links for downloading the libraries below.

Method 6: Settings for users with limited rights

This solution to the problem is aimed only at system administrators who have encountered difficulties in running AutoCAD on computers of other users of the local network. In most cases, a cooperative network involves the use of accounts with limited rights. This is what causes the problem in question. The developers point out that this can be fixed only by granting rights to such files:

C: \\ Users \\% USERNAME% \\ AppData \\ Local \\ Autodesk \\ AutoCAD 2015
C: \\ Users \\% USERNAME% \\ AppData \\ Roaming \\ Autodesk \\ AutoCAD 2015
HKEY_CURRENT_USER \\ Software \\ Autodesk \\ AutoCAD \\ R20.0 \\ ACAD-E001
HKEY_CURRENT_USER \\ Software \\ Autodesk \\ AutoCAD \\ R20.0 \\ ACAD-E001: 409

After that, you should restart your PC and try again to start the software.

Method 7: reinstalling the program

It is worth resorting to using the current method only when the above options have not yielded any result. AutoCAD, like any other software, might not install correctly on the PC, which provoked problems with launch. In such cases, only a banal reinstallation will help. However, you should uninstall the software correctly in order to accurately get rid of all residual files.

Even a novice user can figure it out with reinstalling, but we still recommend reading the additional guide on this topic in order to repeat all the steps exactly and not get the same launch problems.

After you have successfully solved the problem, you can safely proceed to the full use of AutoCAD. It will be useful for novice users to study the training materials on this topic in order to quickly understand the workflow and master the interaction with the basic tools and functions.

The AutoCAD software package, created by Autodesk, is intended for the production of drawings of parts, buildings, diagrams and other engineering documents. Sometimes, when using this program, problems arise, namely, "AutoCAD" does not start.

Problems installing Autocad

The first thing a new user of this software package encounters is installation. In most cases it goes unnoticed, but sometimes the AutoCAD installation does not start or abruptly terminates. This event is often accompanied by the appearance of a small window with a message containing an error code and other information required for diagnostics.

Error 1603

This issue is caused by the Microsoft MSI installer not working properly. It manifests itself for the following reasons:

• There are too many files in the Temp folder on the system partition of the hard drive. Solution: delete the folder.
• Insufficient free space on the system hard disk partition. Temporary files necessary for the installation of AutoCAD are extracted there. Solution: remove unused programs, clean the folders located in the "Libraries", "Downloads" and desktop in Windows 7,8,10. Clearing the browser cache will also help free up space.
• Program conflict. Solution: disable during installation all applications running in the background (located in the notification bar next to the clock) and close all active programs.

To speed up the search for the cause of the installation failure, you can use a tool from Autodesk called AIDA.

.NET Platform Not Installed Error

Another "AutoCAD" is the absence or disabling of the FrameWork .NET package versions 4.5 and 4.6. Most often it manifests itself on versions of AutoCAD 2016 and 2017 after updating Windows components.

There are two solutions to this problem:

• Check for updates KB3081452, KB3081448, KB3081449 in Windows 10. If they are missing, use the Update Center or manually download and install them.

• Check the presence of the required component in the system. To do this, in the "Control Panel" you need to go to the "Programs and Features" section. If the framework is installed, then you need to go to the subsection "Enabling and disabling Windows components" and select the required component. Otherwise, download it from the Microsoft website and do the above manipulations.

Error 1606 or 1317

It manifests itself if there are traces left on the hard disk or in the registry from the installation of another version of AutoCAD. The problem is solved in the following ways.

Method 1. Checking the registry. To do this, you need to launch its editor, called by the regedit command in the Run window (called from the Start menu or by using the Win key combination (a flag on the keyboard) and R). In the key tree on the left side of the window, you need to find the Common Documents key, located at HKEY_LOCAL_MACHINE\u003e Software\u003e Microsoft\u003e Windows\u003e CurrentVersion\u003e Explorer\u003e Shell Folders. Its type should be REG_SZ and data should be C: \\ Users \\ Public \\ Documents. If the key is missing, then you need to add it: "Edit"\u003e "New"\u003e "String parameter". After creating a new key, you need to check if the folder specified in the key exists.

Method 2. Removing unnecessary files using the Microsoft Fix It utility. You can download it on the official website.

Error "The system cannot open the specified device or file"

The next reason why AutoCAD does not start is the absence of the necessary file or its blocking by the antivirus. Therefore, to fix the problem you need:

• Disable antivirus software.
• Run the installer with administrator rights or disable User Account Control in the "Control Panel".
• Clear the TEMP folder and re-run the installer.

If these measures turned out to be useless, then you need to re-download the installer from the official website or torrent tracker.

Problems at first start and during use

Sometimes after installation "AutoCAD" does not start. As well as during the installation process, while loading its components and interface, a window may appear indicating a specific error. But this is not always the case. For example, when the loading indicator window appears and disappears, and then nothing happens.

Error "Application could not be started due to incorrect parallel configuration"

This malfunction occurs for two reasons: incorrect installation of the program itself and absence, damage or conflict between the components of the Microsoft Visual C ++ libraries. In the first case, you will need to completely remove AutoCAD followed by reinstallation.

To solve the second problem you need:

1. Reinstall C ++ Libraries. Information on how to do this and where to download the required materials can be found in the Autodesk Knowledge Base under "How to remove and reinstall Microsoft Visual C ++ Runtime Libraries".
2. Restart your computer.
3. In the "Programs and Features" section, find the installed CAD system, select and click the "Change / Remove" button. In the window that opens, you need to check the box next to the "Restore" item and start the process.
4. After the restoration is complete, start AutoCAD.

The error "The program could not be started because the MSVCR110.dll file is missing on the computer"

The appearance of the problem is related to the disappearance of the specified file from the Visual C ++ library. In some cases the component name may change to "MSVCP110.dll". There are 3 ways to eliminate the error:

Method 1. If you have a computer with identical software, you can copy the required file from it to the problem PC.

Method 2. Use the recovery tool included in the 2012 C ++ library installer for 32-bit and 64-bit systems.

Method 3. Reinstall all Microsoft Visual C ++ libraries.

The problem "AutoCAD starts and closes immediately"

Most often, this error appears after the program "freezes" and forcibly closes it through the task manager. In this case, the license file is sometimes damaged, due to which the program cannot start. To fix the problem, you need to clear the Flexnet folder of all files. It is located on the system partition of the hard disk in the ProgramData directory. After that, the program should work.

The second cause of this problem is an outdated video card driver. You can download them from the manufacturers' websites. If the update does not bring results, then you need to disable hardware graphics acceleration. This is done as follows:

• Right-click to bring up the context menu of the shortcut that launches AutoCAD and select Properties.
• At the end of the line "Object" add "/ nohardware".
• Run the program.

If the above measures did not have any effect, then you need to reinstall the software package. How to completely uninstall it can be found in the Autodesk Knowledgebase under "perform a complete uninstall".

There are many reasons why AutoCAD does not start, but they are all successfully solved by Autodesk technical support specialists.

A similar, very unpleasant problem occurs quite often and is often not accompanied by anything, neither lags nor errors.

The reasons for the occurrence and ways of eliminating the situation when AutoCAD does not start will be described below.

This is exactly the situation where no accompanying information appears (no errors and the system log is empty).

The problem lies in a file called "CascadeInfo.cas", which you just need to delete so that it will be recreated at startup.

Its location will depend on the version of the operating system.

On Windows XP, it is located in Autodesk \\ Adlm under Documents and Settings \\ All Users \\ Application Data.

In Windows 7 in the "ProgramData" directory.

You can also use the "Search" functionality, for this enter the name "CascadeInfo.cas" in the search bar and click "Find".

Upon completion, the searched object will appear in the list, and the address of its location will also be indicated next to it.

Incorrect operation of the protection system

AutoCAD does not start and an error appears with the text: "The security system (software license manager) is not responding or is not installed correctly."

The main and most common solution is to manipulate the Flexnet service.

As an addition, it is worth mentioning one more point that such a problem may also arise due to the use of an outdated component of the IE operating system. Check for the latest updates, if any are found, take all the suggested actions.

Parallel configuration

The error text looks like this: "Failed to start the application due to incorrect parallel configuration."

"Parallel configuration" is the cause of many problems, and not only with the AutoCAD program, but the solutions for this error are the same.

The reason is in Visual C ++

Due to the fact that the Microsoft® Visual C ++ component does not work correctly, you should reinstall it, for this you will need the following:

1. Open the "Programs and Features" section, then "Add or Remove Programs".
2. In the list, find all lines starting with "Microsoft Visual C ++" and delete them.
3. After uninstalling, restart your computer.
4. Reinstall all the "C ++" components, having previously downloaded them according to the bitness of your system, after installation, restart your computer again.

Alternatively, go to the folder where AutoCAD is installed, find the "VCRedist" folder and run "vcredist.msi".

Using sxstrace.exe

"Sxstrace.exe" is a diagnostic tool that allows you to determine with which module the parallel configuration is causing the error.

User with limited access rights

To check if the problem lies in the local policy setting, create a new user account or temporarily assign an existing local administrator rights.

If the user has successfully launched the program and the rest of the components start without any errors, then the problem is precisely in the access rights.

It should be borne in mind that for the correct launch of AutoCAD and its operation, the user must have access to the following folders and registry keys:

• C: \\ Users \\% USERNAME% \\ AppData \\ Local \\ Autodesk \\ AutoCAD 2015,
• C: \\ Users \\% USERNAME% \\ AppData \\ Roaming \\ Autodesk \\ AutoCAD 2015,
• HKEY_CURRENT_USER \\ Software \\ Autodesk \\ AutoCAD \\ R20.0 \\ ACAD-E001,
• HKEY_CURRENT_USER \\ Software \\ Autodesk \\ AutoCAD \\ R20.0 \\ ACAD-E001: 409.

AutoCAD does not open by double clicking on dwg

If after double-clicking on an object created in the AutoCAD program with the ".dwg" extension, nothing starts, try the following actions:

As a conclusion, it should be said that the situations when Autocad 2017 does not start (there may be other versions) are different and the reasons may not only be those described above, but they may also be related to other factors. For example, incompatible operating system components or updates were installed that prevent the software from working correctly. And also: interference of third-party components, antiviruses, firewalls; incorrect uninstallation of AutoDesk products, followed by reinstallation.

The solution to this problem can be banal reinstallation of the program and restart of the computer.
