I visit many places. here was one reply. i do not get credit for it.
If the game is already installed on your computer (does not start from a disk)
from administrator account, go to the directory that has the .exe file, right click on it, create shortcut.
Next right click on the shortcut you just created and click properties
then click the advanced tab and un-check run with different credentials and click ok
then apply, until you're back to the shortcut.
Now move the shortcut to the limited user's desktop C:\Documents and Settings\kids_account\Desktop
he mentioned the checkbox might be checked or unchecked. was not sure.
convinced it will work though.
