So, you've gotten a new machine (or a recent update) with Windows 10, and you've installed older Autodesk Products (generally 2017 and older), and your products fail to run or crash consistently during simple operations. Most likely this is tied to what version of Windows 10 you are running.
Hit Windows+I (I as in India) to open Settings. In the Settings window, navigate to System and click on that. In the System panel look and click on About at the bottom of the left-hand list. Scroll down a bit and you’ll see the information you’re after. See if you are running Windows 10 Creators Update (v1703):
If you are running Version 1703 or higher, this is where the problem lies. This version of Windows comes with .NET 4.7 pre-installed. You will not be able to remove or downgrade it to an earlier version of .NET, and this version of .NET is known to cause issues with older Autodesk Products.
Here's the choices you have:
Windows 10 Creators Update (v1703) comes with an embedded .NET Framework 4.7.
Rolling back the Creators Update is the only way to remove .NET Framework 4.7 once it has been installed (see How to rollback & uninstall Windows 10 Creators Update). You have 10 days after the update to roll back, otherwise you may have to re-install the operating system and block the Creators update in the future updates (the link above explains that process). You may also try doing a system restore to an earlier version (See Recovery options in Windows 10).
Windows 10 Creators New Install (v1703) comes with an embedded .NET Framework 4.7.
- With new installations for this version of Windows, .NET cannot be rolled back, so you need to either obtain an earlier version of Windows 10 and reinstall the operating system or upgrade to the latest Autodesk software.
