Windows 7 incorporates a mode that allows you to run programs written for earlier versions of Windows. Some old programs may run poorly or cease to run on Windows 7. When this happens you can find a solution by invoking the Program Compatibility troubleshooter.
Program Compatibility can automatically detect and fix common problems that prevent older programs from installing or running correctly. To start the troubleshooter wizard type Program Compatibility in the Start menu search text box and click the Run programs made for previous versions of Windows link. You can also open the troubleshooter by right-clicking a program’s icon or shortcut, and then clicking Troubleshoot compatibility.
It is recommended to run the program using administrative privileges and you can do this from the first page of the wizard through the Advanced link. The troubleshooter tries to detect all programs installed on your system and presents a list of these, including an option to browse for an unlisted program.
It is also recommended to not use the troubleshooter on older antivirus programs, disk utilities, or other system programs, because using outdated programs of this type might cause data loss or create a security risk.
