I need to uninstall ATI's video drivers after upgrading from Vista to 7 due to some incompatibility. However, one of the steps is to uninstall all the assembly's with a certain public key token from C:\Windows\Assembly. The issue is that when I right click Uninstall on any assembly, I get Access Denied. I tried running Explorer.exe as admin, no luck. And the \Assembly folder doesn't even have a security properties tab, so I can't even add admin to have full control. Any ideas?

Can you try to boot in Safe Mode and uninstall the Assemblies or change the ACLs?Ray

The Assembly Cache Viewer is a Windows shell extension that allows you to view and manipulate the contents of the global assembly cache using Windows Explorer. For more information please fo through the link mentioned below:http://msdn2.microsoft.com/en-us/library/34149zk3(vs.80).aspxIn additon, you can refer to the following link:http://blogs.msdn.com/cumgranosalis/archive/2005/10/03/476275.aspxHope this information helps

Under Vista I was able to delete/uninstall assemblies in the GAC as follows: I created a shortcut with the Target: %SystemRoot%\explorer.exe C:\Windows\assembly I would then right-click on this shortcut and select "Run as administrator" which would bring up Windows Explorer displaying the GAC shell extention with admin privileges. I could uninstall assemblies by selecting them and hitting Delete (or right-click and select "Uninstall"). This worked (most of the time) under Vista. Under Windows 7 this no longer works, I always get "Access is denied" Anyone know why/how to get around this?

I have the same issue. Did you ever figure this out?

If you're asking me, I finally gave up and turned off UAC, lots fewer headaches this way.Reminder: If someones post answers your question, please click "Mark as Answer".

Thank you Robinson for being typically Microsoft in your response. You did not read the question. You did not put an ounce of consideration into answering it. You found one search term - GAC - and shoved us off to the most basic and least informative possible link, a link that is Pre-Win7 when THE QUESTION WAS ABOUT WIN7!!! Yes you are truly Microsoft material.

The only way I got this to work on Windows 7 was: Start -> Run -> Command Prompt (as administrator) Find your version gacutil.exe. The one I used was here: C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin C:\>C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\gacutil /u YourAssemblyWithNoExtension

I needed to do the same thing on Win7 x64. Booting into safe mode I was able to easily remove all the ATI GAC pieces at once. Had to boot back to normal mode in order to install the new ATI drivers.
