Is there a way to disable the driver installation on the offline backup installer's? My PC already have the required drivers and I don't want the installer to mess with the registry because it makes some other games unable to start.

Context?

Which game? What drivers? Which system?

All together. All games, all drivers, including C++ 2008, DirectX, etc. Making the offline installer ignore the included drivers within the installer. Simply disabling every kind of additional installation other than just the game itself.

>disable driver update
wut? do you mean auto install ms visual?

Not likely. The installers as far as I know don't have command line parameters to force non-installation of certain dependencies. The best you could do would be to install the game on a guest OS (VM) and port the install files you want to the host OS. It would be then up to each individual game whether it ports successfully with a simple game folder copy.
And then there are the issues with missing library dependencies. Messy stuff.

I see. Before this new type of installer you was able to select whatever you want to install and what not. Then nowdays it suddenly forcefully installed Microsoft Visual C++ 2008, 2012, and DirectX 9.0c every single time with nearily every single game I have in the library. It is as ridiculous as I have MVC++2015 64 bit on the program list at least 4 times, despite I installed nothing on the laptop since 2 months after the windows reinstall other than 4 GOG games.

When I'm buying a game I'm fully aware of its requirement both hardware side and software side, I don't want an installer that arbitrarily mess with my system. I hate Steam because it enforce a client to install and play games, but at least it not forcefuly install these, only include the installer for manual use. GOG should do the same.
