Do it overnight when you go to bed.... and see what happens. I don't really remember the details, but I'm pretty sure in task manager it reads not responding even though it doing it's thing. It does take about 2-3 hours for the patch to install, so about all you can do is give it time.However.... if you interrupt the process and cancel out... then you need to uninstall and start over from the very beginning. The patch will not work once you cancel out... doing that breaks the game. Found that out on my own. Because, I too, thought the patch stalled and canceled out that first time I tried patching it. Had to uninstall everything Witcher and start from the very beginning.... and just let the EE patch itself while I slept... next morning it was all ready to go.Might be a good idea to just "copy" the whole Witcher directory to another directory, and then activate The EE patch. That is, If you have the HDD space for it... I found out that you can even play the game from the self-copied directory. It even finds the saved games. The only thing that you can't do with that copied save is install official patches to. The install doesn't notice that user made directory and will only patch the game that the windows registery knows about. Anyway the main point to this is that if the EE patch doesn't finish, at least you can just copy the backup witcher over the orginal install, and won't have to go thru the long process of uninstalling and reinstalling. Which in itself takes about an hour.Also, I guess, to be safe, don't install the game in Programs Files, if you are on Vista.... I've never tried Vista, myself; but I've heard that games installed in there tend to generally, have problems.
