micktiegs_8: They told me that it was perfectly fine on their end. Told me to make sure I had zero trace of Galaxy on my machine to double check, what directory to delete etc. In the end they offered a refund for my gifter (I said I didn't want that, because I'd like to be able to have the game for future machines) or there was nothing they can do for me. Basically, use galaxy or fail.
READ - after all of this, I downloaded galaxy, installed it and the DLC magically appeared. Didn't even have to log into it or anything. I simply installed galaxy, ran the standalone game that I already had installed (without galaxy active). Galaxy is the issue, but someone doesn't seem to 'notice'.
Assuming this is one of those can't play without Galaxy issues, I would say most likely there was still a trace of Galaxy on your machine, probably in the registry most likely assuming you removed the hidden ProgramData folder. Using a registry cleaner like CCleaner may have fixed it. There isn't much they can do about that other than improve the way Galaxy uninstalls in the future versions and makes sure nothing is left behind in the process. Obviously if any part of Galaxy is left the game thinks Galaxy is there and it messes up (issues launching, ect) because it's really not, I've seen a few people report such issue.
And since one can mess up their PC by messing with the registry, GOG support telling people to re-install Galaxy would be the better solution in this case unfortunately...

As far as focusing less on Galaxy, hell compared to other game companies with clients GOG isn't really focused on it much at all. Sure they advertise it, but they are slow to add any meaningful changes and it honestly feels they have bitten off more than they can chew compared to Valve with Steam, EA with Origin, or hell even MS with the Xbox app on Windows 10. That feels more complete and stable compared to Galaxy and it probably has been in development about the same amount of time or even less.
GOG just needs to hire more people, and based on their now hiring section they are having trouble getting them.
synfresh: Yet wasn't there a sizeable wishlist entry for a client?
There was.
And according to data released by CD... GOG has like doubled or tripled in size since Galaxy and the Witcher 3. Sure Witcher 3 has a lot to do with that, but nearly 1 million people are playing it with Galaxy. So you can disagree with the concept of clients, but there is no mistake that gamers by large want a client and that GOG is benefiting greatly by having one.
