JetBrains Meta Programming System not working


Whenever I try to run the batch script to run MPS, it opens for a split second then immediately closes.

Trying to run it via the command line gives me the following message: "Jetbrains/MPS was unexpected at this time."

I posted the question also on their forum, but I don't seem to get an answer, so maybe someone else had this problem as well.

EDIT: For clarification, I am using Windows 10 on 64 bits, and have tried both version 203.7148.1199 and version 202.8194.1069, installed via the toolbox app and via the standalone installer. I also want to mention that my system meets the requirements to run the program.

EDIT 2: I found out that it works but only if it is installed in the C drive, not in any other drive.


Solution

  • The problem was the path in which MPS was installed. Apparently, it's a bug that I just discovered and the characters '(' or ')' in the installation path make MPS just not run. Probably the bat script doesn't take them right into account or something.
