Windows Update pushed Service Pack 2, but when I try to install it, the installation fails. Update says it has installed the update, then asks me to press the restart button. When I do, I get another screen (no restart) that goes through stage 1 and stage 2, reboots the system, then runs stage 3 to 100%. Then I get a message saying, "Service Pack did not install. Reverting changes." Which it does, and I am back to square one. I have validated my windows installation, and I do shut down Trend Micro Internet Security Pro before doing the update.
PS I have seen references to a Vlite program, but I do not have this installed.
For others who may have this problem in the future:
I have two hard disks, one with linux, which is what I actually boot from, and another with the system that came with the computer (vista). The service pack apparently will not install properly if it sees other hard disks with other operating systems on them. Solution: unplug the other disk/s while doing the upgrade.
