I tested a few other installers on the desktop, tried all the compatibility options, and none of them will work.

jest mart - I really don’t think it’s corrupted.  Every single one of the old installers (with that same icon) that I’ve tried to run do not work.  And every single one of the newer ones that I’ve tried do work.

LaurieA - thanks very much for the links to Virtual XP.  I’ll check it out.

hborre & LaurieA - When I run the installer, how exactly do I cancel the search?

bagginsbill & hborre - To turn off Kaspersky I’ve been clicking on the little icon in bottom bar of my desktop to “Pause Protection”.  But looking now in the Windows Task Manager, it’s still showing up in Processes, and the numbers under "Memory (Private Working Set)" are still moving/changing.  Does that mean it’s still doing something, even though I’ve supposedly turned it off?  Anyway, I tried to click on it and “End Process” but it won’t let me.  I get this message: “The operation could not be completed. Access is denied.”  Do you have any ideas on how I can completely shut it off?
