As the name implies, 0x80070005 FIX will simply attempt to repair the dreaded 0x80070005 error messages when trying to register dll files while installing certain Windows components or programs. Sometimes you will not get this specific error number, but just an Installation Failed message. This tool will in most cases also repair these errors, for example: Internet Explorer 7 installation failure. It will accomplish repairing these errors by restoring your computer to the original installation default security settings. Because restoring your security settings to its defaults can't be undone, 0x80070005 FIX will automatically create a System Restore Point for you. Note: If you do not have any 0x80070005 errors or Installation problems, do not run this tool, it will be unnecessary.
