Recipe 4.9. Troubleshooting Application Compatibility


You want to run a legacy application, you've run the Application Compatibility Wizard, and you've tried the Application Compatibility Toolkit, but the program still is causing problems.

It could have left behind Registry keys or files and folders on your hard disk. Follow the advice in Recipe 4.2 after you uninstall the program to make sure that you've removed all its traces. Then reinstall the application.
