Just to let all know. Many are getting an error when trying to install. Here is the fix:
Go here: en.thewitcher.com/ee_manual/
D/L parts 1 and 2 (just a bit over 512MB total)
Run the Install from your D/L folder.
All will work perfectly!
Thanks for this, it was defaulting to another language and giving me errors left and right. Must have somehow got a bad file or two when preloading a few days ago.
