forrtl: severe (9): permission to access file denied, unit 23, file C:\WINDOWS\system32\file.cio

[Ben Fisher]

Hello,

I am currently attempting to calibrate for snowfall parameters (SFTMP and SMTMP) and after one simulation it freezes on, "end_yr_of_sim= 2017". The model is running fine in ArcSWAT and I used WinMerge to ensure that the ArcSWAT and SWATCUP TxtInOut folders are identical. 

I ran the debug version of the executable in a cmd prompt and came up with, "forrtl: severe (9): permission to access file denied, unit 23, file C:\WINDOWS\system32\file.cio".

I've tried using several iterations of the swat executable with the same errors.

Any help is much appreciated!

Thanks,

Ben

There could be mistake in defining the time periods.

Clearly mentioned calibration period, warmup period, file.cio, .def files.
