I pulled out a 5 year old Acer (it's been shut down for about 14 months) so I could use it to run Red Alert 2. (I can only get RA2 to run on Win 7 systems which is what this Acer is running)
Yesterday, I booted the machine, played around with it for a bit and then inserted the CD and ran the setup. The setup was successful and I played the game for an hour or so. Later, I rebooted and played again for a bit. All was well.
This morning, I noticed the system had run a Windows update and installed a bunch of stuff. It had also scheduled another update for the next time I shutdown my computer (or 3am tomorrow).
I didn't think anything of it and tried to play Red Alert. Nothing happened when I clicked the icon. RA checks to make sure that a valid CD is in the drive before it runs. This test seemed to be failing although I didn't figure that out until after I had uninstalled RA2.
I disabled (and eventually uninstalled) an anti-virus program called AVG 2013 although I'm not sure why this would have helped since it was enabled when I successfully installed yesterday.
Now, when I click the setup.exe on the CD ROM (it's readable as I can copy it to the hard drive), I get the user account control dialog box asking me if I want to run the program and when I click Yes, nothing happens.
Task manager indicates that "Setup.exe" is running and then another "SETUP.EXE" (all caps) appears in the list and then disappears in about a second. The original Setup.exe also disappears from the list.
The Acer is running Win 7 (x64) Home Premium, SP1.
Can anyone suggest what might have gone wrong?
