I have a clients machine to do some work on. I tried to install an application program but it failed saying SP1 needed to be installed. I started the SP1 Update but on restart, it had some sort of error. I shutdown, restarted, went to Windows Update which said there were no important updates. I tried to install the application program again but got the same error.
How can I tell if SP1 has been installed?
How can I force a re -update of SP1?
Thanks in advance.
