AutoCAD 2012-2014 crashes when launched & opening / closing files
When launching, opening a file, or clicking a ribbon command or menu in AutoCAD 2012, 2013, and 2014 on Windows 7, 8, 8.1, and 10 systems, a fatal error is encountered and the program crashes, such as the following:
The .NET Framework 4.7 has been installed. Please note that Windows 10 is not a supported platform for AutoCAD 2014 and older.
You could also see an excessive amount of Chromium process being executed while starting AutoCAD.
Edit the acad.exe.config file (or acadlt.exe.config for AutoCAD LT):
- Open the following file in Notepad:C:\Program Files\Autodesk\AutoCAD 20xx\acad.exe.configTip: Right-click the file and choose “Open with” and then pick Notepad as the application, or launch Notepad directly and then click its File menu, choose Open, and then select “All Types” in the file type menu to select the file.
- Copy-paste the following line of code between the <runtime></runtime> tags (Note: This is one line–no line break, as it may seem to have depending on the width of this web page article):<AppContextSwitchOverrides value=”Switch.System.Windows.Input.Stylus.DisableStylusAndTouchSupport=true”/>
For example:<!–All assemblies in AutoCAD are fully trusted so there’s no point generating publisher evidence–>
- Save and close the file.Note: If the operating system forces you to save to another location, be sure the file does not end up with a .txt extension and then manually copy it into the AutoCAD program folder, overwriting the existing one.Tip #1: If when you copy in the file and do not get a prompt to overwrite the existing one, then the extension was changed. You may see and edit the extension by right-clicking the file and choosing Properties.
Tip #2: This solution also works for DWG TrueView. The file to edit is dwgviewr.exe.config.
- Roll back any recent Windows updates, particularly for .NET Framework 4.7 (see Autodesk products not working after installing .NET Framework 4.7).
- Use Windows System Restore to revert to a point before the crashes started. Declining future Windows updates should keep your AutoCAD programs running, although this is not recommended. Not updating a Windows system could put you at risk by missing out on installing security patches and other important updates from Microsoft.
- Upgrade to a newer version of AutoCAD, although, it is possible that .NET Framework 4.7 can still be a conflicting factor.
- Install Autodesk Licensing Hotfix – POODLE SSL v3 vulnerability (CVE-2014-3566).
- Run the product on a supported version of Windows and avoid installing .NET Framework 4.7. Here are links to the system requirements for AutoCAD versions 2012, 2013, and 2014:System Requirements for AutoCAD 2012
