forcing windowed mode through a registry edit. Check the thread for details on that one.
If the windowed mode works there's a way to set it up so it looks exactly like fullscreen. Info on that is in the sticky thread as well.
Thanks for the suggestions. The one above is the only suggestion I haven't tried.
I'm having this problem as well (on Windows 7 32bit). I never get error messages. Like the OP, the game simply doesn't launch...nothing happens. I've tried the following suggestions gleaned from around the net with no success so far:
Updating drivers for GPU
Uninstalling and reinstalling the game (multiple times now)
Running the installer as administrator
Launching the game as administrator (trying both the launcher and the witcher.exe)
Creating and editing launcher (and witcher.exe) shortcuts to ignore Minimum Sys
reqs (I never got the related error message, but thought I might try it anyway).
Both installing and uninstalling the TAGES protection (not sure if this is relevant to
the GOG version, but did it anyway).
Downloading and installing the 1.5 patch (this wouldn't install; I assume because the
GOG Enhanced Edition includes this patch?)
Running in compatibility mode (XP SP2)
Anyway, I expect I'll try the last remaining suggestion of the windowed mode from the other thread. If nothing happens, well, I guess I'll wait until I have some spare hard drive space to create an XP partition on a future computer. Thanks for the help thread!
EDIT: As a follow-up, I tried last night to edit the registry to make it run in windowed mode, but the "fullscreen" isn't even listed in the registry for the Witcher to edit. Very disappointing.
Also, to add to things I've tried above, I've downloaded and installed DirectX 9 & 10, just in case. I've also checked and rechecked the integrity of the install files.
Does anywhere out there have any other ideas to get this game to run on a Windows 7 laptop? (also, thanks for all the suggestions in the forums - it looks like they worked for other people)
