Hello!
There might be a possibility that you have a conflicting window setting.
You can try running the game using a new Administrator account. You can do this in the User Accounts interface.
1. Click on the Start button.
2. Click on Control Panel.
3. Locate the small Control Panel sub-window at the top left of the window.
- If it says Switch to Category View, you are in the correct viewing mode.
- If it says Switch to Classic View, click on the text to switch to the correct view.
4. Double-click on the User Accounts icon.
5. Click on the Add button.
6. Choose a user name and password.
7. Make sure to give the account full Administrator abilities.
8. Once the account is created, you will be able to restart and log in with the new Administrator account.
