So, I've been having the same issue, as long as most of the posts in here and what i did was add the modapi launcher to steam and apparently worked:Cornucopia wrote: ↑Sat Sep 11, 2021 12:39 pm (obligatory "I made an account just to ask one question" comment)
Alrightie, so I was able to get the ModAPI to work with every mod EXCEPT for ones that much be launched via the Launcher (aka Dark Injections, in this case)
Whenever I launch the game after installing Dark Injections, it tells me to launch the game via the ModAPI. Which... I'm already doing. When I uninstall Dark Injections, Spore opens fine. It will run all my other mods except Dark Injection, which is a pain since I love to use Dark Injections for infinite complexity (and I do not believe there's a working mod out there for just that, if there is that please tell me lol)
For some more information: I am using the Steam edition of Spore, have both DLCs, and have used Dark Injections just fine on Spore before. This only began happening after I had wiped my computer (to fix some technical issues), reinstalled API and Spore, and I attempted to use the API after a reset (yes, it was working fine until I reset my computer for a Windows update. Thanks, Windows!). I have attempted to uninstall and reinstall the API, Spore, and Dark Injections before, however this didn't change anything. Can't really find anymore comments about some sort of issue similar to this...
The option is on the bottom left corner, you select "add a non-steam game..." and then browse for the launcher and the just start it from steam (i added the original, not the shortcut, idk of it works with the desktop shortcut), make sure to remove admin privileges from steam and then it should work.
I hope it works for everyone else.
