To be 100% with you. I’m surprised this isn’t already an option. In fact its sad it isn’t. But, you should really let people select the .exe for infinity to use.
Now you might be thinking… why? Well. I’m sure a lot of us here use mods in our games. Take Fallout 4. I run my game from my Mod Organizer 2 using F4SE. I can make a shortcut to launch the game this way… but I can’t have infinity run that shortcut.
