This is a joke ? Where is the patch 1.04 ?
When I buy a game, I wish that this game was complete.
Why steam version have the patch 1.04 and not gog version ?
I want to play it in stereoscopy, for that I need patch 1.04.

So please, sell the whole game !

Just install the universal update. It updates the game to version 1.06.17.0155

What universal update and can you tell me where it lives please

what's the installer version you have ? v1 or v2 ? (it has nothing to do with the internal game build)

the game got a new installer (version 2) about a week ago , it should be the lastest game release avaible. I can't be 100% sure since i didn't play it recently.

there were a patch for the v1 installer, since quite some time , but this installer is no more avaible.

note :
v1 installer : either the file(s) has(ve) no version number in its/their filename , or 1.x.x.x
v2 installer : file(s) names always have this format 2.x.x.x
