This software is designed to be used in conjunction with an uninstalling program that was use to track the installation of new software. It is designed to remove invalid Class, Interface, and other installed files keys. This software will remove any entry that is not valid, contains a non-existent file or invalid path. If the entry in the registry contains an incorrect path, or and invalid quotation mark, comma, period, backslash, or another character that is not valid the key will be removed. An undo file will be create each time the program is run. Then Undo file should contain a double backslash for a file path. The previous file will be over written. The Registry Cleaner will automatically repair the font folder and the Recycle Bin folder on Rebooting after use. The Snapshot utility is designed to show you which files have been replaced with older versions or modified during an installation. It will also show you which files have been added or deleted to your machine. It will not remove an files that may have been added during an installation. Uninstallers will remove the files that they tracked during the installation. The Snapshot utility file can then be used to help you completely remove the installation. Some dll files are not removed by uninstallers, so now you can see if the file was added by the software you are uninstalling. ERROR MESSAGES If you get an error during the registering of a DLL or OCX (ActiveX) files try replacing the file and rerun the Registry Cleaner. If you still get the error you can bypass the file next time by entering the file name below as shown :(filename = 1) The file name will be displayed in the lower window of the interface at the time the error occurs. If you still get the error then you need to enter the previous file instead. [BadFiles] odbccu32.dll=1 apitrap.dll=1 qd3d.dll=1
