Here's a post which Jimmy made a while back that should help you:
=====
Some games will work with limited accounts after they have been installed
and
run once either using an administrator account, or by temporarily changing
the
limited user account(s) to an admin account in Control Panel / User
Accounts,
just for the purpose of running the game the first time in order to be able
to
install the necessary files and create the keys in the registry that it
needs to
function, but may not be able to due to the restrictive nature of limited
accounts.
If that mouthful doesn't resolve the issue, use the "Run As.." command
instead:
1. Click Start / Control Panel / User Accounts / Create a New Account /
Name the Account: "able2play" (without quotes) / Next Pick: "Computer-
Administrator" & Click "Create Account";
2. Click on your new able2play account and Create a Password for it;
3. When your limited user wants to play a game that requires Administrator
privileges they can Right-Click the shortcut to that game / Click Run
As... /
"The Following User": able2play and enter the password. Simple as that!
I know what you're thinking: That defeats the purpose of the limited user
account.
To secure the "able2play" account so that it can't be used to logon to the
computer:
What I do is add a shortcut to the windows logoff routine into the RUN key
of the
able2play registry. I made a reg patch to simplify this process if you wish
to use it:
4. Logon to the "able2play" account,
5. <ONLY RUN THIS PATCH USING THE "ABLE2PLAY" ACCOUNT>
Save this patch to your drive and then doubleclick it to install it to
your registry.

or
*Instead of using the reg patch, click Start / Run / regedt32 / browse
to:
[HKCU\SOFTWARE\ Microsoft\Windows\CurrentVersion\Run] and
Click Edit / New / String value / ValueName: logoff / Value data: logoff
From now on, if anyone logs on with the "able2play" account, the computer
will log
them off immediately. They will not gain access to an administrators
desktop!
