Revision history [back]

I have two versions of PSS/E installed, 32 and 33, and am trying to use python code to solve a power flow solution in PSS/E 32. I get this error when I try to run my python code:

CHKPRG Error Bad revision number 32 for program PSSE Was expecting 33

This is the first time I'm trying to use PSSE v32 with python after I've installed v33, so the first time I've seen this error.

Is there anything I can do to correct it?

Thanks!
