Hi
We are getting below error on few of CAS servers when we try to upgrade to Exchange 2010 SP3 while uninstalling the IU for SP2
"Setup wizard for update rollup6 for Exchange Server 2010 Service Pack 2 (KB2746164) ended prematurely because of an error.Your system has not been modified.To install this program at a later time, Please run the installation again"
We checked UAC its disabled for the server.
Tried running with run as administrator in the source patch file as well still did not help
Tried opening the source file as copy as path in command prompt and running them as well still it did not help
We tried manually uninstalling the Interim Update but still we get the same above error
Any help would be much appreciated.
