A customer has a Windows 7 machine that was never updated to SP1. I was having trouble installing any updates until I uninstalled his Kaspersky AV (which wasn't working anyway), ran System restore to a restore point 2 weeks ago, and ran SFC ?SCANNOW. Now Windows Update appears to work, but the only update offered - after installing about 50 of them - is IE 11, which fails because IE 11 requires SP1.
I uninstalled IE 9 because it is working, now IE 8 works as well as IE 8 does these days.
His Garmin Express keeps telling me that it needs .NET Framework 4.0. The only .NET on the machine is 4.5. No other .NET versions are ever offered - even as Optional updates.
I downloaded SP1 as an ISO and burned it to DVD. Setup starts to run, but then tells me that the installation was not successful, and that I should restart and try again - which does not work.
What do I have to do to get this computer to behave?
