GameRager: Id' rather they put up maybe a FAQ with such info for such baseline users than dumb down everything to meet the lowest common denominator.
Keeping the install location to one that could cause problems is dumb. Especially when it's only used because it's the default. A lot of old games save to the install directory, so it's not a smart move to keep it as it is at all. Moving it to one that doesn't cause conflicts on the other hand is a smart move.
Especially when not everyone who is going to be playing the games has admin rights.
You're only thinking of yourself here. You're not thinking of what's good for GOG or what would benefit the majority of users. If you insist on installing to Program Files, that's fine. But you'll just have to do what I do every time and change the install location.
