Assembly Cache Viewer - Install Failed - Server 2008 GAC

q: when we try to copy a .dll file into the GAC on Server 2008, we get an error.  Assembly Cache Viewer - Install Failed  / Access is denied:



a: With UAC enabled, the fastest and easiest way to install a .dll file into the Windows Server 2008 GAC is:

  1. log out.  Log back in using the actual local administrator account.
  2. open two copies of Windows Explorer (one at the location of the dll) and (one at c:\windows\assembly) 
  3. drag the file from one window to the other.
