TheDudeLebowski: What am I missing? Which file is Galaxy accessing to load the game? How do I change it?
First exit Galaxy. Look in the game files, using Oblivion as an example, you should see something like "goggame-1458058109.info". Open this file in notepad (a code editor would be better though, such as VS Code), and you should make a backup first just in case.
You should see something like this:
{
"category": "launcher",
"isPrimary": true,
"languages": [
"*"
],
"name": "The Elder Scrolls IV: Oblivion",
"path": "OblivionLauncher.exe",
"type": "FileTask"
},
The "path" part is what you need to modify, you need to point it to the new exe. Be sure to modify the right one though, as other stuff is also placed here like tools that show up under MORE -> Other. So the one that is directed to the games exe or launcher should be the right one. Save and start Galaxy.
