Hmmm... And what about those Microsoft Hotfixes that: 1) Don't have any BuildDate, like KB923789, KB886903 (Screenshot 1) 2) A wrong BuildDate format, like KB917734 (Screenshot 2) How will nLite react? Would this explain why nLite is asking me many times if I want to overwrite or not an already existing fix (dll) thruout the hotfix implementation? Regards, Johnny
