Well, as I said, this second time around (after having waited with the 'modifying game files' message for 8 hours the first time), I uninstalled EVERYTHING Witcher-related, uninstalled all .net framework files, cleaned out my registry with RegScrubXP and CCleaner, and then reinstalled all .net framework files from the ground up (1.1, 2.0, 2.0 SP1, 3.0, 3.0 SP1, plus all updates and hotfixes), and then installed Windows XP SP 3 for good measure, as well.I then reinstalled the Witcher to a fresh 1.0 state on my hard drive, and tried the 'universal extractor' trick on the EE upgrade files this time. As of right now, I'm just passing the two-hour mark with the 'modifying game files' message... Can anyone tell me for sure that it's actually at all worthwhile to wait much longer for it? Is it actually likely to do anything, or am i just going to wait another 8 hours and have to abort? Should it sound like the installation is accessing my hard-drive? (it really hasn't made a peep in the two hours, which makes me wonder whether it's doing anything at all!)Any and all advice would be greatly appreciated. This is starting to get seriously frustrating...Thanks very much,RoA
