Naismith1: I have exactly the same problem, I get the same message while trying to install GOG galaxy. I then downloaded the game installer and got the same error message:
Runtime Error (at 53:3765): Cuold not call proc
My laptop is running Windows 8.1.
I cannot explain more, I'm not very good at computers.
I just bought a bunch of games I cannot install. I'm disappointed
You can install your games. Goto the website, select your account and then games. Find the game you want to install. Click on download offline/back up installers. Download the files there - these are the game installers. Download them all fully. When they are all downloaded, put them in the same folder and double click on the exe, just like installing any software. I would suggest install to an non windows folder, like c:/mygames.
It's very simple, just basic computer use. You can also save those installer files on a seperate external hard drive, so you can install anywhere, keep a backup etc. This is the only reason to shop here at the end of the day, you buy it, you get the files and keep it, no need for clients, or online or anything else.
