Hi, I swear on an old computer that after installing this stuff pack to an old game, uninstalling the whole sims 2 and then re-installing the sims 2, would make this pack's stuff appear in the new game despite me not installing it. Did the computer remember it somehow despite the uninstallation? PS, I use the stuff pack, not the happy holiday version of the sims 2.

Sounds a bit weird. What is showing ingame to make you think the pack is showing up?

Check the "...\TSData\Res\Catalog\Bins" folder for the basegame in the installation location, and look for a "H05.bundle" or "H06.bundle" file.

Did you make sure everything was cleared out before reinstalling? In some cases, files can hang back in certain parts of the file system, especially the hidden "apps" location.

Thanks, it was an old computer but I'll take note in the future.

Sounds like left over windows registory files from the previous installation to me,

And on one of my old computer installations of The Sims 2 Happy Holiday Stuff Pack or when I first installed my copy a long time ago santa clause went around the game without a beard with a glitched out head
