HunchBluntley: You should know that you don't have to use GOG Galaxy for running your GOG games (unless you want to play online multiplayer in one of the games that uses Galaxy to implement that, or if you absolutely
must have Galaxy achievements). Client software such as Galaxy can simplify installation & updating of games quite a bit...when the client actually works as intended; Galaxy is still an early-ish beta product, though, so it's got quite a few kinks which need to be worked out.
Attached are some instructions on how to download & install a game from your library via your web browser of choice -- just pretend my
Stasis reference is actually talking about whatever game you're trying to install. (I really should get around to updating the text on those one of these days. =) )
THANK YOU. YOU ARE SUCH A GREAT HELP TO ME.
