I remember canceling an installation a couple of days ago and since then I get this when trying to install anything else. I don't remember what it was I canceled but this is what it tells me:

"Error 1500. Another installation in progress. You must complete that installation before continuing this one"

I checked around Yahoo answers and found that many people had this same problem, but non of the answerers worked for me. On guy recommended "Windows Installer CleanUp Utility" but I downloaded it and its installation was stopped with the same problem.


Help!
