Just a suggestion... I had to hunt around to see where the launcher actually downloaded the patch to! Turns out it was \Documents\Witcher 2\Downloads

GOG, could you please make this a little more clear in future updates? Thanks! Now back to the game!

guys in quest "in the claws of madness" after ifinish the quest i climb the ledder and i cant exit the house please help

Mine won't update past 1.1 and running the game patcher from the game directory yields the message that the game is already updated to the latest version. You have to love that. Looks like 1.1 is as far as I can go on mine. Anyone encounter this issue and get it resolved?

You sure you updated to 1.1? I would never, ever trust the patcher in the game directory.

If you manually install the GOG-specific 1.1 from where your bonus content is, then manually install the 1.2 and 1.2 -> 1.3 patches from the Witcher site, you should be able to update without any problems.

i cant register you cant fill or write anything in the boxes nor i can download patches

Do you know what version do you have installed ?

Check the game installation folder.
Do you have a "Readme" file there?

If you have that file, It may have the version at the beginning.
Something like this:
The Witcher 2: Assassins of Kings v. 2.0 ReadMe file

NOTE: The firsts version (1.0, 1.1, 1.2) doesn't say a thing.
