Installation of Windows Vista Service Pack 1 unsuccessful
Posted on 2011-02-24
I recently upgraded a Windows XP SP3 on a Dell Precision T3500 to Windows Vista. I then tried to install Service Pack 1 for Vista several times with no success. After the third stage of installation it says Installation not successful, reverting changes. I have tried uninstalling my Antivirus Program and still no luck. There is no other message other than the one mentioned above. Does anyone know what I can do to successfully install the Service Pack 1?
Any help as always greatly appreciated.
