I cannot activate the game. I have downloaded Witcher 2 four times now on wired and wireless connection. I get the same error on patcher "installed game version is invalid or incomplete" Yes I installed with UAC off, firewall off, antivirus disabled on Windows 7 64bit.

I'll never buy another game from gog. I have bought 50 or so games from steam and never had a problem. I sent an email to gog tech support and never got a response.

I'm sorry to hear about your predicament. I also had the same error during my first attempt of installation.

Afterwards I uninstalled the game, disabled my Avira antivirus and reinstalled again. That did the trick. I'm using Windows 7 32-bit.

I don't understand why the need for the Patcher though..

Sorry to hear, I'm on Win 7 64bit Pro with SP1 and I didn't have any problems installing and running the game. Why don't you contact the support before you start crying about spilled milk, just a suggestion.

GoG's version is already patched! That's why your version is INVALID! And activation is a problem with server for any version, not GoG's. Hope you can play the fraking game and enjoy it soon! Once you're into it, you'll never remember these petty issues again!

I did use the gog downloader. And installed it with antivirus disabled. I'll try to download using browser.

Patcher automatically runs the first time you install the game.

And I have contacted support, with no response.

RageGT, are you saying that game is not activating because activation servers are down?

Lucky you. I think that's the part which does not work on my version...

Oh, and you might have mis-understood what I wrote: the "normal" or "browser" method is the one failing all the time. Altho with the last install it seems even the downloader has failed.

I think the program should be cut up to smaller pieces...maybe it'd help?

Hm...It's sad, a lot of people got it right, gog's downloader checking the integrity of every 10mb chunks of the files and RE-checks at install, I don't get it. In my humble opinion...I would download it from a 3rd party source and then just put the CD Key you got from GoG.

Sorry the "conventionnal way" did'nt work out for you.

What 3rd party source would that be?

Well, I certainly don't know what has failed here. I just can't play a game and now I've wasted my d/l quota plus a hell of a lot of time.

And the support is silent.

So yeah, I'm now in the same camp the orig poster is, as the title suggests...

I don't think it should. I'm pretty sure it didn't for me. I'm on Win7 64 bit and it DLed and installed without issues (I disabled antivirus, ran as admin, and disconnected from internet when I installed)

Considering every other version, as far as I know, requires connecting to securom servers to activate, while GoG's doesn't, that'd be pretty piss poor advice since I doubt your key would work on another version of the game since your GoG key shouldn't even be in the securom database.

Just saying.

If, by some chance, this is exactly what the OP did (it's pretty unclear what he even means by activating since there's no activating in the GoG version), then that would be his problem.

It doesn't matter whether patcher runs or not. Game does not launch from launcher. When I click launch on the Wolf, I get a message "Use launcher to start game" Brilliant!

I'm talking about torrenting any cracked version and not applying the crack, and no, it's not illegal 'cause legally you own the game, and backups are legit, then.

I'm pretty sure the GoG Key is as legit as any other Key, wether or not it goes to SecuROM or not. Maybe the gog's one goes to CDP directly and not SecuROM server...Even if that was, I don't think they did two sets of differents CD Keys for the game, that would be a bit silly.

Even if...You paid the game, I'm sure the gog's support will help you at the moment they are not so threathened by the amount of work TW2's launch made. You got nothing to loose using the method I would have chosen, it either works or you'r at the start case.

BTW, I don't get you guys who tell the game was already patched...Mine patched himself when i installed it (a window popped at install screen).

*sigh* The gog game does not send the key out to a server, GoG, Securom, any server. It only sends the key o ut if you select "Register Game" like everyone else. Everyone else, DOES have to send a key out to be read by securom before playing, whether they registered or not.

So, if you were to download a cracked torrent without applying the crack (in which case, why bother, and why not just download an uncracked torrent), then unless the cracked torrent was the torrent of the GoG version of the game, then it's going to make a call to the securom servers. And, since GoG is DRM free, I'd be willing to bet a healthy buck that it is going to fail if you were to do that since there's absolutely no reason for your GoG serial key to be there.

None of which answers the question in any way that the OP has since the GoG game has no DRM and has no activation, making his question just nearly impossible to answer without making stabbing guesses in the dark.
