Add "Read" and "Read and Execute" to the local group "Users" for the file:

"C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config"

I have windows 10 on my PC, I can’t uninstall net framework. I have all my permissions to send for all my folders. Everyone has full access. I believe it might be a graphics card issue. My computer is about seven years old.

Hello @SIA_Design, 

This could be a graphics issue but it could also be a .Net Framework issue. 

1.Check the Operating System needed & the required updates by reviewing the system requirements for the software, Certified Graphics Card Drivers  by checking the manufacturer's website

2. Make sure you have an updated graphics card driver (Assign the correct Graphics Card)

3. As an optional step to get a complete clean removal of the .NET files, run the .NET Framework Cleanup Tool: 

.NET Framework Cleanup Tool User's Guide 

The tool will not remove versions of .NET that have been built into the Windows operating system (see What version of the .NET Framework is included in what version of the OS?). It will only affect what you see listed in Programs and Features for which you could uninstall yourself. On non-Windows XP systems, it may be necessary to right-click the EXE for the tool and choose "Run as administrator." If errors occur in the utility, run it again until no errors occur.

Keep us posted.

No solution. I bought a new computer and no more error. 
Thanks.

I spent a lot of time trying to find the solution to this - in fact, I removed all my Autodesk product installation without a solution, removed all .net /aspnet recommendations, registry keys and all.

What eventually worked for me ---

I copied all the content inside

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG 

(ensured the machine.config file had full control permission for users)

And pasted the content inside

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config

Clicked yes to overwrite all files.

Goodluck
