Revision history [back]

Hi all

I am using a legacy PSSE version 34.5. The is a dlls that I have used many times in the past, but I can no longer load in PSSE. Has anyone else had this issue?

ierr = psspy.addmodellibrary('..\\case\\241024_LTU_PSSE_PSCAD_CUO_fix\\SMASC_G190_344_IVF150.dll')

returns ierr=1 -> file not found

Messages for API ADDMODELLIBRARY Library not found (000284) "..\case\241024LTUPSSEPSCADCUOfix\SMASCG190344IVF150.dll"

The file is definitely there. Also I can load another dll which is located in the same place. When I try to load the file manually through the PSSE GUI I get a similar error. So it seems the that PSSE, which used to be happy with this file, now has a problem with it. The file has not changed; it is binary identical to the version I have loaded many times.
