"Unable to open master control file"

i wanted to do a static study of my assembly.
But when i press run this study, i get the error above.

I have tried doing the same simulation on a different pc. But it gave the same result.

I have no idea how to fix it or where even to start looking for a fix.

because after googling the error, it s still not realy clear what's wrong ..
