Demitrix2k: You no longer need to convert bat to .exe, you can link .bat files in Galaxy 2.0
my earlier guide in here was for Galaxy 1.2 which is now outdated, there are way better tools making this actually way way simpler, so il post a quick tutorial since its super easy now, few steps.

1. make a bat file with ( open notepad, paste contents, save as .bat extension)

2. paste and configure according to how you want it to launch, i do it like this
"C:\Mod Organizer 2\ModOrganizer.exe" -p "GOG-DemitriX-NV" "moshortcut://:New Vegas"

3. Go to your game in Galaxy 2.0 and click the button on the right side of play which is the options menu
select manage installation > configure
Cant find what im describing? here is a video https://streamable.com/aomtat

4. tick and enable custom executable and click in the bottom "add another executable / arguments" and select the bat file wherever you so placed it( might aswell put it in game directory to keep it clean.)

5. select it as default by clicking "default executable" so when you click play, it will use that one instead of the default that comes with installation.

So if you've done my old method, its the steps to making a bat file, then you simply just add it as another executable and make it the default to run when you click play.

Haku__: Hey Demitrix2k !
Any chance you can help me too ? I have exactly the same problem but with Morrowind and I did what you said here in the last post. I made that .bat file and changed the executable but GoG Galaxy just won't start it sadly :( . My line for the bat file is without the profile part. I tried both with it or without it and that small change the other guy in that thread did /swaping places/ too and did not work. I tried to double click just the bat file and everything would start - MO2 and then the game. I don't know if that proves the .bat file is fine. But then the GoG Galaxy just won't start it - no visible errors. Using the last versons of eveything

SkoLL297: That was so helpful! Works for FO3 as well.

marcew44: Thank you for that, i managed to do it here and although the Galaxy overlay doesn't start for some reason, both cloud saves and playtime counter works!

Demitrix2k: Im glad people are still benefiting from this method.

Demitrix2k: ****EDIT*****
THIS WAS THE SOLUTION IN 2019, EASIER AND LESS COMPLICATED METHOD IS FOUND IN POST 16

Updated as of 5/5/2024

Ok so i think have found a working solution for this issue its quite simple
video showcase here of how it works and demonstrating it working

Once you have mod organizer running the way you want it, note down the profile name and open a notepad
copy and paste this and modify it to your liking, afterwards "save as" and save it as anythingyouwant.bat Demitrix2k: Now the thing is, you can launch the game perfectly with this method without opening mod organizer, the issue is you still have no galaxy client overlay and playcounter, we fix this by converting the bat script into a executable .exe file

Edit:
People requested the actual script i myself used which is a modified version of the one from github

You can use this exactly as i did in the video

Once converted to an exe rename the old FalloutNVLauncher to something else and keep it as a backup, and name your newly created exe to FalloutNVLauncher and place it in the game folder.

Now you can launch Mod organizer with your profile AND have the galaxy client fully functional as it normally is through the galaxy client!

CyrodiilWarrior: any modern & simple method to get GOG Galaxy Overlay to work with Mod Organizer 2 (MO2) for Fallout: London ?

CyrodiilWarrior: Hello. I'm using Fallout London with Mod Organizer 2 (MO2). On GOG, I tried the following argument:

"G:\Modding\MO2" "moshortcut://:Fallout London"

Each time I launch the game through GOG, I get the following error:
"Cannot start MO2"
"This error typically happens because an antivirus is preventing Mod Organizer from starting programs. Add an exclusion for Mod Organizer's installation folder in your antivirus and try again."

I've tried adding this exclusion for Malwarebytes without luck and no idea about Windows Defender... even tried running GOG Galaxy with admin.
