new computer sounds kick ass. I'm jealous. 

Thanks! I found the problem thanks to your instructions.

The instructions on the EA web site left out a line in regards to the registry editing. I found the problem under HkeyLocalMachine > Software> Microsoft > Windows > Current Version > Application Data. I cant remember what the files were called, but when I scrolled down to 'the sims' section, there was several entries about University Life and Best of Business. Once I deleted those, the games re-installed just fine.


Thanks again for all the help. 

Ok, just to clarify: Yes, I have the two collections that just came out.

Yes, store version came with University Life Collection and it is EP99.

The only version currently installed is Double Deluxe.

I deleted the files for University Life, Best of Business, Seasons, Store version and all the related stuff packs.

I also removed the registry entries for all the above, except Double Deluxe.

I'm really thinking that it is not my computer's problem,power-wise or memory wise,  but I think that there is something hidden on the Collection files that is not uninstalling with the rest of the files.

Thanks for the help tho.

Hello. I'm hopeful this forum can help me with a problem.

I had this installed:

Sims 2 Double Deluxe
University Life Collection
Best of Business Collection

Up until 2 days ago, when I installed Seasons. Seasons appeared to install correctly. When I tried to play the game, Seasons would load for about a minute, then I got an error message "The application will now terminate" and it did. So, I went to the EA games site and found that to fix this problem, I would have to do an complete uninstall and reinstall of all four expansions. The un-installer that came with the games would not work. I tried to uninstall from the add/remove panel and that would not work. So, I then found instructions on how to do a manual uninstall. This I was able to do, I deleted the games from my hard drive and removed the registry entries.

I was able to re-install both Double Deluxe and Seasons and both work fine on my computer. BUT When I tried to re-install University Life or Best of Business, I get an error message "All packs are already installed."

I've been trying to find an answer on how to get Uni. Life and BOB back on my machine, but my search is leading me nowhere. I've tried CCleaner, un-installing securom, copying the disks to the hard drive and installing from it (also didn't work.)

Any help?
