When it tries to open , the program just exits out by itself.
I just sent you an email, but here is the solution for everyone else:
There are three things to try:
In the Universe Sandbox folder, that you can likely find here:
C:\Program Files\Universe Sandbox
or
C:\Program Files (x86)\Universe Sandbox
1
Trying running
update.exe.
2
If that doesn't work, go into the Prerequisites folder and run
UpdateFix.exe and then run
update.exe again.
3
If it's still not working download the latest
universe-sandbox-setup.exe and reinstall on top of the existing installation:
