Hi there, I am having similar problems to you. Whenever I use my Windows XP Service Pack 2 CD with nLite, it always gives me 2 errors. One says that the CAB file in the i386 directory of the Windows XP installation files is corrupted and then the preceding error, which I assume is related to the first error, reads: "CabLib Extract ERROR while extracting files from cabinet archive: Corrupt cabinet." I am no nLite Pro, and there probably is a simple explanation for this, so if there is, please tell me. I'm sorry I can't solve your problem Diablo1, but I think that someone is bound to solve it eventually. Keep searching the net, you may just find a solution!
