PaladinNO: Do you also have the base game installed? When you launch the main .exe directly from the x64-folder, what happens?
Also, have you downloaded and installed the same version of the base game, as the Phantom Liberty expansion?

EvolvingChimps: What Paladin is saying, is that you need the full version of Cyberpunk2077 to run Phantom Liberty, and that if you have a steam copy of CP2077, it will not work with a GOG copy of PL.

If you own CP2077 as well as PL on GOG, and have tried to install it but it still won't run, we'll need some more information. What's your system setup? CPU/GPU/RAM/Display?

Have you tried reinstalling the redistributables that come with CP2077? It should be in the options under the Galaxy tab for CP2077.

999jiggy: yes i have the main game installed, just tried launching it through the main .exe from the x64-folder and it still launches the game without phantom liberty. and yes both are the same version 2.12a999jiggy: I own CP2077 and PL on GOG, it's able to run but the problem is that it runs without the dlc even though i paid and installed the dlc. Where do i find the redistributables? what galaxy tab is it under?

this is still what my main menu looks like after purchasing and installing pl

EvolvingChimps: So what you'll want to do is run a Verify/Repair which is located here:

Sometimes when you first buy an expansion and install it, you have to verify the game through Galaxy to get it to register.

999jiggy: oh yea also tried that twice already, still the same issue. The game installs the update/dlc but it still doesn't recognize pl is installed when i launch the game.

I decided to do a clean install under the cd projekt red support page and it fixed my problem, phantom liberty is now showing up but thanks again for the help chooms!
