unknown error installing/removing sims complete..

[BroadwayBeckons]

I’m sorry for the difficulty that you are having with The Sims.

An improper installation or corruption of the game data can not only prevent the game from loading, but can cause the game to crash at seemingly random but very specific points in the game. When such an occurrence happens, it’s best to manually remove all of the components to make sure that next installation does not run into the same issues. To do a manual uninstall for The Sims and expansion follow these steps (instructions referencing an expansion you do not own should be ignored):

Delete the game folders.

Click on the Start button.
Click on the Run button.
Type C:\Program Files\Maxis or into the text field, and press OK.
Note : If you changed the install path for the game during the initial installation, you will need to type that into the text field in lieu of the previous path.
Right-click on the The Sims folder and select Delete.
When prompted if you are sure, select Yes.
Once deleted, click on the Start button.
Click on All Programs.
Click on the Maxis folder.
Right-click on the The Sims folder and select Delete.
When prompted if you are sure, select Yes.
