Microsoft scanned this file for viruses. Microsoft used the most current virus-detection software that was available on the date that the file was posted. The file is stored on security-enhanced servers that help to prevent any unauthorized changes to the file. The Office 97 File and Registry Eraser utility removes most of the files and Windows registry settings that remain on the computer after you remove Office 97. This utility is designed to be run after you run the Setup program for Office 97 and click Remove All to remove Office 97. When you run the Office 97 File and Registry Eraser utility, it removes shared system components. The Internet Explorer Active Desktop requires these components, and does not work correctly after the files are removed. To restore the Active Desktop, reinstall the Comcat.dll file.
