Hmm I haven't gotten to the point where you have to enter the key yet, maybe I should try it out... Is it ok to re-slip the same folder with the same SP3 using the latest nLite (the one that was already slipstreamed using beta 2)?
What exactly was the problem with slipstreaming SP3 in Vista? I added SP3 into XP (English and German versions) using 1.4.5 beta 2 in Vista x64. Both seem to at least boot properly. Will I run into problems using those CDs later?
