The upset on Vista is slightly different as in the XP version.
Computer --> Local disk (C:)--> users --> [your user name] --> Documents--> EA Games --> TheSims 2 --> Downloads
(make sure it's the same location as the neighbourhood and Savedsims folders)
Putting it in any other folder won't make it show ingame. If the Downloads folder doesn't show, make a new one.

It seems the version 2.9 of this file won't work with my computer... It is a .rar file; is that right? When I first downloaded it, it wanted to open with iTunes(don't ask me why, lol), though, I changed it to open with the Sims 2 game... Should I change it back to open with iTunes?
And something else though, I had saved the Insimenator file(version 2.4b) I had used before on my XP, which is a PACKAGE file, and this one does work on my Vista now...
Should I just keep using the 2.4b version, or is there a way to make the 2.9 version work with my computer?
