Witcher 2 PC version owners who didn't buy the game from GOG, you can register your game on GOG now.GOG version owners - you don't have to do above said step. It's automatically on GOG for you.
EE Patch is fully out now. Though, looks like servers getting hammered or
having installation issues...
Many of the Goodies got EE updated versions, as well [New Comic Book, New Triss Pics, Updated Manual, Updated Soundtrack, etc] - so you might wanna DL what you need or just DL the entire 2.8 GB Goodies EE Pack.
EDIT 1:
If you want to manually install the EE upgrade or just need the files missing to update from TW2 Regular-to-EE, go here and grab what you need:
TW2: EE - Manual Install Files.EDIT 2:
Basically, I DL'ed to the folder where you put all the EE Upgrade files:
All the Part 0 files for the language packs (EXE files for installing language packs).
Re-DL'ed Main Files Part 0, 1, and 2 [Part 1 and 2 are rumored to be corrupted; Part 0 is the necessary EXE file].
Ran TWEE_Patch.EXE.
All went fine and can run the game.
EDIT 3:
If you have ALREADY finished the game [recent or long ago], the game created a End Credits Save.
If you Load that, It'll give you the EXTRA slideshow-style] results for your actions.
AWESOME!
