Windows 2000 with Service Pack 2 or later includes a tool that you can use to configure compatibility mode settings for applications. This can enable an older application to run on Windows 2000 when it might otherwise experience problems.

By default, Windows doesn't display compatibility settings. To expose these settings, open a command prompt, and enter the following command. (If you didn't install Windows in \winnt, replace \winnt with the proper location.)

Regsvr32 \winnt\apppatch\slayerui.dll

After registering the DLL, create a shortcut to the application for which you want to configure compatibility settings. Right-click the shortcut, and select Properties. On the Compatibility tab, select the Run In Compatibility Mode check box, and choose a compatibility layer from the drop-down list. When you launch the application from the shortcut, Windows uses settings specific to the selected compatibility mode to run the application.

If you need more control over application compatibility, try the Application Compatibility utility (Apcompat.exe), which you'll find in the Support folder on the Windows 2000 CD. This tool offers options and features you can use to fine-tune application compatibility.
