I have an NVIDIA GTX 1060 3GB, and I found subprocess.exe.
Quick edit: Just to cover all the bases and avoid missing anything important, I tried running subprocess.exe and received this error.
I actually have the same graphics card, so we know that works! Subprocess.exe won't be able to run on its own, the error you see when you do that is normal.
I wonder if it's screwing up when it tries to construct the path to subprocess? What's the path to the folder where it's installed? Is there a game.log too?
Oh neat! I haven't met anyone in a while with the same card.
I figured that was what was going on with subprocess.exe but I wanted to make sure I hadn't missed anything important, so I gave it a try anyway.
I did find game.log though, apparently I'm just blind! As you can see I also tried launching it from my desktop to see if that had any effect but I got the same blank white screen and suspended process as usual.
As a side note to avoid confusion I have unzipped the folder, I just kept the same filename.
I've put a new version up and if you've got time, it'd be great if you could take a look. It uses a different method to construct the file path to subprocess.exe and fixes a bug where errors weren't making it into the log.
Well it seems to be working now! When I first unzipped and launched the game it loaded fully to the main menu but when I closed it and launched it again to make sure it wasn't a fluke it froze immediately. After some troubleshooting I deleted the folder it was in and unzipped it into a fresh one it seems to be working for the time being! I've tried closing and relaunching the game to make sure it still works, and it seems stable, thank you so much for all your help!
