Contact the product developer. I've run into a lot of games that were
written by people who had no clue how system permissions work in the real
world, alas...
Not only games...:-( plus in most cases I've come accross the vendors will
usually insist on their program requiring full administrative rights for all
users *sigh*
In most cases all you need to do is grant write permissions to the program's
installation directory (to limit this, check out which files and/or
subdirectories you really need to grant writing to, not that important if
it's "only" a game). Sometimes you also need to do the same for the
program's registry keys under HKEY_LOCAL_MACHINE.
In case of The Sims this would be C:\Program Files\Maxis\The Sims\ (assuming
default installation paths on an English system) and the registry subtree
HKLM\Software\Maxis\The Sims. If that doesn't suffice check for other keys
relating to the game.
