Patch 1.4 of COD W@W wont work :|

Tried the "Run as administrator" work round (like patch 1.2) - Won't work, a possible solution is

1. Open the Administrative Tools control panel.
2. Open Local Security Policy.
3. On the left side of the window that opens, highlight the Software Restriction Policies folder by left clicking on it once.
4. Go to the Action menu and press New Software Restriction Policies.
5. Now, in the left side of the window, some icons should have appeared. One of them is called Enforcement, and it's icon should look like blue 1's and 0's.
6. Right click it and press properties.
7. In the window that opens, check the "All users except local administrators" radio button.
BUT, i dont appear to have "Local Security Policy" on XP64 !

Can anyone help point me where this may be located ?

Cheers
