Incorrect side-by-side configurations
I just got finished restoring my Vista Home Premium computer to factory settings. I'm trying to download all my favorite software. Avast antivirus and Firefox got downloaded, no problem.
However, Yahoo Instant Messenger just doesn't want to start up. It'll install, but when I try to launch it, it'll say "the application has failed to start because its side-by-side configuration is incorrect. Please see the application event log for more detail."
Uninstalling it and re-installing it doesn't do jack didley.
Ok, maybe Yahoo is a fluke. However, the same problem happens with Open Office, the free office suite.
What the hell's going on, here?! Why can't I install anything?
