First of all, sorry for my English, im spanish.
So I've downloaded Witcher 2 al installed with the GoG downloader and installer but when Its done I clic on the icon this message appears:
"The Witcher 2 Application Launcher stop working" (well, it shows it in spanish obiously)
Ive updated the GoG launcher with the last patch but nothing changes.
Please help, i wanna play!

I forgot to say its completely original. Its the especial edition of the normal version of the game.

Have you tried turning off your internet before starting the launcher? If that doesn't work, you should be able to use the witcher2.exe file in the /bin folder of the game's installation to start the game.

yaaaay thanks bro it worked when i use witcher2.exe and configurator.exe thanks bro :D
