A user in my office has installed XP upgrade over ME and now none of her Norton programs (SysWrk 2003 pro) are working. I can't locate any uninstall programs associated with the installation. And no Norton programs appear in XP's remove programs lists. And I cannot get a new installation of the program to run nor can I run any either WinDr or CleanSweep from the CD(it keeps saying to remove the "old" programs first). Using XP's system configuration utility I have halted all Norton tasks from running at startup, but still no luck. Any solution come to mind?....
