Do you know about the MCPR removal tool found at the top of this page under Useful Links? MCPR will remove any traces of the software that may remain after you uninstalled. Reboot the computer and then follow the instructions in this link and run the McAfee preinstall tool http://service.mcafee.com/faqdocument.aspx?id=TS100119
Let us know how this works for you
Thanks Tom, but I just re-installed successfully, so I think I'll leave well enough alone. One final reboot to make sure I can bring it up successfully.
