when I try to start Outcast, it plays the intro, then starts the launcher, but if I click 'new game' I get a popup saying 'OUTCAST DVD missing. Please insert DVD : DATA'
I checked the Outcast.ini, and it does mention the right path to the Data folder (dvd_path=B:\Games\Outcast\Data)
I suppose I could make an iso containing the content of the Data folder, mount it in daemon tools and change the path to the virtual disk, but I'm kind of confused as to why it doesn't work in the first place.
EDIT1: the iso thing works. So for those suffering from a similar problem, this is a viable temporary fix.
EDIT2: another option for those running Vista/Win7 is to make a symbolic link to the data folder on another partition and point the ini there
EDIT3: FIXED! Thanks GOG! (see solution)

It works at my end.
Does your machine have a cd/dvd drive ?

Yes, it does. Why?
Tried downloading the setup again and reinstalled, just in case. Didn't help.

There was another game doing that on machines without a drive. Installing a virtual one solved the problem for that game, i was thinking if it was something similar.
Feel like trying to reinstall to default location to see if it makes a difference ? That's where i installed it and i had no problems starting the game.

Ah, yes. That was the first thing I tried, since it seems to fix things for no sane reason way too often. But no, that didn't work. I'll send a ticket to support then. Figured that there might be an easy solution, so I posted here first :)
Not really, I'm kind of OCD-ish about the organizations of my drives :p I'm going to try the iso thing first, if that doesn't work I'll think about it. But thanks for the suggestion.
EDIT: iso trick works, so the problem seems to be that the game refuses to recognize the Data folder as a disc. Why and why only for me? I do not know.

It's a bit annoying yes, but look at the bright side, you can play it now ;)
You installed it to default location ?

As I said, I kind of find that a more annoying fix than my current one. But I'll try it, for Science!
EDIT: Well well, that fixes it. Idle observation: the partition I originally installed to is called 'DATA' itself could there be some kind of silly conflict here? The drive label is mentioned in the .ini: [general]
autorun=0
cd_intro_label=Windows7
cd_music_label=Windows7
first_audio_track=0
dvd_path=C:\Program Files\GOG.com\Outcast\Data
VS
[general]
autorun=0
cd_intro_label=DATA
cd_music_label=DATA
first_audio_track=0
dvd_path=B:\Games\Outcast\Data
EDIT2: making a symbolic link on C:\ pointing to the data folder and pointing the ini there also works, even easier than the iso trick

d:\games\outcast
So no. But I've never had a problem with that before. Even with old DOS games it wasn't a problem. I might try that just to see if I can get it running though.

Already done. :D

Good luck. I have a felling it's going to work. Fingers crossed ;)

FIXED IT! Navagon, is your drive named 'DATA' too? Because I renamed it to DATA2 and changed the label in the .ini and now it works.
EDIT: OK, after a reinstall it doesn't. Ignore me please :p

The label on the DVD was 'DATA'
if your drive is named 'DATA', the game assumes it's the CD (pre-dvd days), and will look for the files in a specific directory.
hence the error, I think,
