First of all - I was disappointed, another GOG release doesn't work well under win7 64 bit / Radeon.

But it works quite nice with a little help of virtual machine.
I'm using VMWare player with Windows XP
After installation I've got some problems - GOGLauncher displays annoying "The application has failed to start because the application configuration is incorrect" but starting game using D3DPopTB directly solves the problem.
Because GOGSetup seems not to work under XP you have to use a workaround to set another resolution for a game - You have to install game on windows 7, set up resolution and just copy D3DPopTB.exe to virtual machine overwriting one from clean installation.

Have nice play.
