(2) Try reinstalling all dependancies: Find the folder "Steam\steamapps\common\divinity ii - dragon knight saga\support" in your windows program files folder ("Program Files" on 32 bit OS, "Program Files (x86)" on 64-bit OS)

Uninstall then reinstall every installer you find under this "Support" folder.
