Alright, this is more of a hobby IT problem, but it was still frustrating. I had a crash of Mod Organizer, a tool to organize and maintain Skyrim mods. After the crash, it wouldn’t start any Java programs anymore – all I got was the error message:

failed to determine binary type: 193

I first suspected a problem with Java, but it was something with Mod Organizer itself. I ended up simply re-installing it, overwriting all files in the existing location. That fixed the error, and it even kept my config, modules and load order intact. If you try the same, create a backup first.

Even though I did not look into the root cause after I got it to work, I hope this helps anybody else.
