So I reinstalled the Sims 2 Ult Collection again after a while from it not working.

(Previously it didn't fully launch due to some misplaced files and some corrupted CC)

When I reinstalled it, after it downloaded and booted up, I noticed there was no sound and when I got into the game, there were no neighborhoods. I went into my documents folder and saw that the EA Games files wasn't there, and there was no folder for the Sims 2.

This may be because it said I didn't have enough disk space and it said problems may occur (even though i have lil over 100g free)

Even if I try helping it by making an EA Games folder, nothing happens. My guess is that this is a faulty install, but just incase someone else has had this problem, I'm still posting

You say you have UC. Before you just reinstalled did you do a full and complete uninstall? If a corrupted install was your original problem it could be affectin your current one as well.

My suggestion would be to use Revo Uninstaller and then try reinstalling.

My very first install from Origin was corrupted, and then so was my second as I hadn't totally uninstalled the corrupted install. I was then pointed at Revo, as I'm doin to you, and my 3rd install worked.

yeah, i fully uninstalled, also defragged after. i'll give that a shot though

welp, after 10 days of trying out figure out what was wrong.i realised that my region was set on japan (for a touhou game) and since i guess the game region was set in america and my pcs was in japan it messed up the download

Stop reinstalling that can make you troubles. Always go into Origin, right click on the UC and select repair. Make a backup first.

Sims 2 doesn't install properly with japanese locale. It is very old known issue. There has been threads about it on MTS.
