tritone: Go here in the menus...
Tools -> Options
Click the "Applications" tab
Find "gogdownloader" under the "Content Type" column
In the "Action" column, make sure the dropdown says "Use GOG.com Downloader".
If it already says that, and it's not working, choose "Use other..." from the list
Now locate where the downloader was unzipped on your harddrive with the "Browse..." button
This might happen when you download a different GOG downloader and either remove/erase the old one or maybe move the folders around.
Hello, I'm having the exact same problem. However gogdonwloader is not in the list.
When I try with Chrome and click on the downloader link nothing happens.
I have tried reinstalling AIR and the GOG-downloader, but with no luck.
