AutoCad not working in Windows 10

Users who have upgraded to the most recent version of Windows – Windows 10 may find that some applications are not working. In my case I found that my security software had disabled itself. I had to reinstall it to get it working again.

It is well known fact that with every new version of Windows including its updates, comes a new set of compatibility issues, registry changes. I was recently told that some user were finding that AutoCAD did not work after the Windows 10 Upgrade.

A posting at their website states:

Windows 10 is not yet an officially supported operating system across the Autodesk product line. Autodesk intends to support many of our key products on Windows 10 and will add products to the list of products supported on Windows 10 as updates and future versions are released. Product Support will provide their best effort to assist customers who have issues with current Autodesk products running on Windows 10.

Not supported does not mean that it will not run. By changing a value in the Windows Registry, you can force it to run.

AutoCad not working in Windows 10

1] If you face this issue, the first thing you want to do is reinstall AutoCAD and see if it solves your problem.

2] AutoCAD requires .NET 4.x. Windows 10 comes with .NET 4.6 Framework installed and it should work with all applications that require older version of .NET Framework. But you need to check if it is installed correctly and enabled.

To do this, Open Control Panel > Programs & Features > Turn Windows features On or Off. Confirm that the .NET Framework 4.6 Advanced Services box is checked.

If you think that the installation may be corrupted, you may need to repair it. See if Microsoft .NET Framework Repair Tool applies to your system and helps you.

3] If this does not help, you can fool AutoCAD installer and make it believe that .NET 4.5 is installed. For that you will have to edit the registry. Please note that using Registry Editor incorrectly can cause serious, system-wide problems that may require you to re-install Windows to correct them. So do create a system restore point first and backup the Registry.

Open Registry Editor by typing regedit in the run dialog box and navigate to the following address:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Client

Find the key called Version. Check its value and note it, you’ll need it for later reference. In my case it is

You have to change its value from (in my case) to But Windows will not let you do so. You will have to  take full control of Windows Registry keys manually or by using our freeware RegOwnIt.

To do this, right click the Client entry on the left side and choose Permissions. Next, click the Advanced the button. Thereafter, locate the Owner section on the top and adjacent to the TrustedInstaller click Change link. You have to change it to Administrators group. Click Apply and OK to save your settings.

Now go back and change the Value of the Version key in Registry Editor to This is the .NET version which AutoCAD is programmed for and checks for, during installation

Now run AutoCAD and see if it works. Once the installation process is complete, go back and change the value from to your own value which you had noted down.

Hope this helps!
