Open the Program Compatibility troubleshooter by clicking the Start button Picture of the Start button, and then clicking Control Panel. In the search box, type troubleshooter, and then click Troubleshooting. Under Programs, click Run programs made for previous versions of Windows.
If the troubleshooter isn't able to fix the problem, try the following:
