Hi there everybody I am using nLite since year and half back, when using it with SP2 I have never encoutered a problem. When I tried to integrate SP3 i found a big problem. I tried to integrate SP3 to my already upgraded SP2 (IE7 WMP11) installation and to my old original SP2 CD. When i integrate SP3 to original (SP2) everything works fine. Whenever I integrate IE7 or WMP11 to my SP3 windows installer becomes corrupt "??" and system refuses to install anything (installer service is not available). Everything else seems to work. The same situation was when i tried to integrate SP3 to SP2 upgraded install CD. Nobody seems to have similar problem. Anyone any ideas ?? Sorry for my english (havent used it a loooong time)
