I had that problem but was able to fix it... somehow. There's a support article on it. But if the solution worked for me, it didn't do so immediately. Damn shame I can't remember what DID work now.
We seriously need Win7 support. But then some games like Overseer were completely unstable to the point of not allowing you to progress at all even on XP. Hopefully GOG will hire on some more testers to fix some of the major problems people are having.

Still defending GOG I see.

What the hell? Nah man, when a release has a problem we should jump on them like rabid dogs! Damn huge corporations like GOG!

So basically, the threshold for whether or not a company/corporation/whatever should be held accountable is how large it is?
Seriously, if this were EA or Activision (or even Valve), everyone would be freaking out and threatening to boycott (and mocking everyone who doesn't immediately start a boycott). :p
That being said: Yeah, there are always going to be problems. Arx still has the savegame bug that periodically makes me lose all interest in it after having to redo an hour of gameplay again. UFO: Aftershock (or 'math, whichever one came first) still is a bit hinky when first running for a lot of people.
But by and large, there are a lot fewer problems than the original release, and that is worth a lot.

Well the games great up till that point. I never even consider that part when recommending psychonauts maybe my mind is trying to forget how rage inducing it was.

I haven't even gotten to that point in the game. I just take it on good authority that it's a terrible part.

Yea its horrible, games got a nice steady difficulty curve and then this section is like running into a brick wall.

I doubt you are as dumb as me, but it took me forever to realize that I was supposed to steer the car with the mouse and not the a and d keys.

You double click the Setup Executable file to initiate the installation process and then you double click on the Game Executable.

Except for the fact that the GOG installer will not actually run on a Win 98 machine at all, it will just error out when run. It only works on XP or higher (it might also work on Win2K).

I've bought a few GoG games and I've not had a problem, but for those who are, have you considered running a virtual machine using Microsoft Virtual PC (it's free) or something similar. You can easily install and use any OS (that you own) from 95 onwards I think (and even DOS if you need to).
I would think that with today's powerful computers, running a GoG game in a VM shouldn't be too much of a problem.

However, VMs don't fully support hardware accelerated video, so any games from the "3D era" are very likely to not work in one. Those that aren't from the "3D era" are pretty much already running in a virtual machine, as most, if not all of them already rely on DOSBox of ScummVM to provide OS compatibility, so adding the extra layer of another VM is just pointless.

Even if someone works on compatibility unforseen issues can arise. Personally only two games don't want to work for me. Divine Divinity likes to crash 100 times in the first dungeon while Arx Fatalis is just unstable on a whole. Out of the 30 or so games I own only a couple of bad apples so it isn't the service man.

Advent Rising crashes like it's nobody's business, but that's just because the game was coded by Helen Keller apparently. Surprisingly it is still a fun game.

Apparently I'm the only person that didn't think the last level was that hard.
It was harder than the rest of the game, but I beat it in probably two sittings.
