Every time I try to run applications like Microsoft Money 2001 or Microsoft word or Excel, Windows Installer tries to reinstall the Product. I get the propmts: "Windows is preparing to install Microsoft Money 2001." "Please wait while Windows Configures Microsoft Money 2001." Then it asks me to insert the application disk. This just started happening, it has never happened before, and I can't think of anything I've done with the OS (Windows XP Home Ed. ) to cause this. I've tried reinstalling the apps, and ran a scnadisk for errors. What's going on with this OS?
