Hi there. I've followed the install instructions to play Fallout London through GOG Fallout 4 but whenever I click the Fallout London launcher or the game in GOG Galaxy the only option is to install it again. I've checked and found that all the game files installed correctly.

If anyone could tell me what's going on or provide some help I'd appreciate it. Thanks in advance for any help.

From the launcher "install" means copy the Fallout London files into your Fallout 4 install. It should play after that.

Ok. I'll try doing that then. Fingers crossed it will play.
Thanks for the reply and the information.

Hi all, so my issue is that when I click on install, and point it to my GOG GOTY, it only copies FO London to its own folder and does not install the game. Every time I click on play after supposedly installing FO London, GOG Galaxy asks me to install again, I have never had a true "play the game" after multiple fresh installs of FO GOTY and FO London. I have watched multiple videos and they are all the same for the install. However, that never works for me. Any ideas on what I am doing wrong?

Where have you installed FO4?

I purchased the GOG version to ensure it all worked, I will tell you that I did not start a FO 4 game before installing FO London. Not sure if that makes a difference or not. So basically, both games are GOG games.

Yes, but whats the install path?
