Hello everyone,

I bought the game yesterday and it worked fine when I launched it automatically just after the installation. Now when I launch goblins quest 3 from the desktop shortcup, I get a black screen and the only way to get out of it is to manually shut down my laptop (a Dell Latitude E6540).

Do you have any solution to this issue ?

Try running the shortcut as admin.

Just in case it still doesn't run after you've tried Gydion's advice to run it as Administrator, check if the ScummVM, which is used to run the game, starts.
You can start it with this file: \Gobliiins Pack\ScummVM\scummvm.exe
(You can try running this as Admin as well => right-click => Run as...)

If it does, click on "Add Game..." and select the Golbins 3 folder and click "Choose". Select the right language version if asked, keep the standard settings by pressing "Ok" and try running the game by with "Start".

The game will run in windowed mode by default this way. When you quit the game and restart the ScummVM, you can choose "Edit Game..." to alter the default settings.

Alternatively, you can leave ScummVM as it is and edit ini files manually. They should be in folders
\Gobliiins Pack\Gobliiins
\Gobliiins Pack\Gobliins 2
\Gobliiins Pack\Goblins 3
for parts 1, 2 and 3 respectively.
Just replace "fullscreen=true" with "fullscreen=false". Also change other options in [scummvm] section as you see fit. I've tested this only with part 1, but it should work with any as ini files look almost identical.

Personally, I prefer editing ini files as you won't have to create another shortcut for ScummVM or open its folder to launch it and just click standard game shortcut as you would normally do. But DeMignon's method works as well so you just choose which is best for you.
