Hi, my friend is having problems with his Windows Installer. It occurs on all the installations/uninstallations that use Windows Installer. He has tried re-installing several times but this only brings another problem about verification of the product which he can't find a solution for. The problem he has, and a solution is at this link: http://kb.wisc.edu/helpdesk/page.php?id=2123 Unfortunately, the solution doesn't seem to work. Does anybody have any other solutions or any advice to get this problem fixed? Any help would be greatly appreciated, thanks.
