To all, Not quite sure this is on par for everyone, but in Paul's case this may or may not be valid. I will throw it out anyway just in case. Has anyone tried the Dial-a-fix tool from DJLizard? It has a section that will try and repair the windows installer and it has helped me from time to time. The tool is located here. http://wiki.djlizard.net/Dial-a-fix It is not foolproof but it automates some fixes to other issues to windows as well. The wiki will explain in detail what it can and can't do. By the way, this works with XP, not Vista. hopefully adding something helpful, Derek Do you want to signoff PCSOFT or just change to Digest mode - visit our web site: http://freepctech.com/pcsoft.shtml
