Ouch.. luckily mine stopped. What a mess.

Edit: It looks like the available DLC are listed in the registry here:

HKEY_CURRENT_USER\Software\CD Projekt RED\The Witcher 2\Downloads

@Morandor
kill the GoG client by CTRL+ALT+DEL and run the GoG downoader again.

Thanks man, removed the two reg items referring to the broken DLCs, and the issue is solved. +1 Rating for being a bro.

Good deal. I'm glad I could help.

Hi, I have gone to HKEY_CURRENT_USER\Software\CD Projekt RED\The Witcher 2 in the Reg Editor but cannot find where downloads are. All it lists is:
(Default)
GameData
Install Status
Language
SerialNumber
Speech

Any ideas what I am doing wrong?

Ok I'm having trouble verifying The Roche Jacket DLC and Troll Trouble keeps loosing server connection after downloading. Does anyone know what the related Registry entries are to those 2 DLCs?

You have to go to
HKEY_CURRENT_USER\Software\CD Projekt RED\The Witcher 2\Downloads


Anyway I don't have the entries 21 and 23.

What do I have to do to download the Troll Trouble DLC then?

I've given up - I've tried all kinda of suggestions and I can't get Troll Trouble. I've seen all kinds of weird errors - infinite re-download loops, invalid code, etc etc.

Patch coming this week should fix the issues.

Hi, thank-you for your response. The problem is that HKEY_CURRENT_USER\Software\CD Projekt RED\The Witcher 2\Downloads does not exist. I only have HKEY_CURRENT_USER\Software\CD Projekt RED\The Witcher 2. I've tried doing a manual search for it and a Find for it but neither can find it.

Not everyone was aware of that fact.
