Hello. Just installed TW2. When I click on the shortcut, the launcher opens just fine. Then I click "Launch game" and a splash screen appears for about 15 seconds, then the launcher immediately comes back. I've tried lowering my graphics settings and updating my video card driver, but this hasn't helped. Any ideas?

http://en.thewitcher.com/community/entry/26/


Game doesn't start, goes back to launcher

Please try the following possible solutions:

1) Turn all settings to Application-Controlled in the Catalyst Control Center.

2) Disable the second GPU from Crossfire configurations until ATI officially adds support for The Witcher 2 in Catalyst drivers.

3) Try running the game in windowed mode.

4) Run the game with horizontal resolution no higher than than 1920, and set the desktop to the same resolution as the game.

5) Ensure that the game was installed with administrator privileges - Windows UAC settings set to minimum or setup.exe from DVD opened with privileges.

Also: Go to User Account Control Settings.

Type in UAC, or go to the System and Security applet.

Click on the "Change User Account Control Settings" link.

(You can also type in this command from the Run menu: C:\Windows\System32\UserAccountControlSettings.exe)

To turn off UAC, move the slider to the Never Notify position, and then click OK. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

It works in windowed mode. This isn't ideal, but whatever I'll deal with it until a fix is released. Thanks!

Now my next question. Can I remap the movement keys from WASD to the arrow keys? I tried to change the input settings on forward and back, but I'm getting "Invalid key. Cannot be re-assigned."

That's coming in next week's patch.

I was able to map them manually as per this: http://www.gamefaqs.com/boards/975399-the-witcher-2-assassins-of-kings/59156459 but it's good to know that there will be an official fix.

I have the same issue. I can see a few "intros" till cdproject then I'm back in the launcher.
I tried everything from http://en.thewitcher.com/community/entry/26/ but nothing helped.
- installed differen graphic drivers incl. beta version
- turned off my 2nd monitor
- turned uac off
- checked the systems event-log
- checked my virus scanner for any entry
- witcher1 dll error fixed due to replacement from the website
- changed game graphic setting from low to high - window / fullscreen - just everything

I wrote to the support but got no response yet. Help ... please

I had the same problem, and even installing the 1.1 patch didn't help.
Tried every known workaround and latest AMD hotfix drivers, to no avail.

Then I uninstalled the game, deleted its folder from "My Documents", deleted every single trace of it from Windows Registry, relaunched the installer with administrative privileges, installed the patch and... BOOM! Finally I'm playing the game in all its glory!
