Greetings! I just registered for this forum so I could post a bit more info, in hopes of leading a few more people to this thread via Google searches and such... I ran into this same problem -- new flash drives prompted for administrator credentials to install. (Actually, they seemed to function anyway, but still gave the scary admin dialog.) I followed many false trails trying to resolve this: permissions on the USBSTOR.INF file, PartMgr.sys upper filter registry entries, etc. There were lots of theories on the InterWeb about what could cause this, but not many answers. Eventually I traced it as JJA did, to an error in setupapi.log about an unsigned version of SysSetup.dll. I guess nLite created a modified version of this file, as well as sfcfiles.dll, to change some behavior during the initial installation of Windows. I didn't see any backups of the original versions of these files, but admittedly I wouldn't have known where to look. Copying clean dlls from a vanilla XP machine fixed it right up. I used nLite v1.3.5 with an XP Pro SP2-slipstreamed-on-SP1 disc as the source. I didn't change anything outside of the nLite GUI options. Despite this problem, I must say that nLite is one fantastic utility. I was able to install XP on a slew of PCs with Intel DP35DP motherboards that need SATA drivers and have no floppy controller to load it with F6 during setup. Ironically, the boards come with a floppy containing the drivers! Thanks for your hard work, and keeping up with the moving target that is Microsoft! -Warren.
