Hello,

I'm getting the following error when trying to run the ArcSWAT on initial run. Is there anyone familiar with such an error?

" Exception caught while trying to run ArcSWAT: Could not load file or assembly 'ArcGIS.Desktop.Mapping, Version=13.2.0.0, Culture=neutral, PublicKeyToken=8fc3cc631e44ad86'. The system cannot find the file specified."

My ArcGIS version is: ArcGIS Pro 3.1.0

ArcSWAT: ArcSWAT Beta Version December 2024

You need to update your version of ArcGIS Pro.

Dear Chris,

Thank you for your suggestion. I am having the similar issue with ArcSWAT. Do you know which version of ArcGIS pro may resolve this issue?

Thank you

Tanvir

I am following up on this thread as I could not determine if a final solution was reached. I am encountering the same problem when attempting to operate ArcSWAT on ArcGIS Pro, as illustrated in the attached screenshot. Thanks in advance for any feedback.

Hello,

I noticed other posts related to the ArcSWAT initial launch error, but as a new user my post does not seem to show up. Anyway, I'm getting the following error when trying to run the ArcSWAT on initial run.

"Exception caught while trying to run ArcSWAT: Could not load file or assembly 'ArcGIS.Desktop.Mapping, Version=13.2.0.0, Culture=neutral, PublicKeyToken=8fc3cc631e44ad86'. The system cannot find the file specified."

My ArcGIS Pro version is: ArcGIS Pro 3.3.5

Thanks,

Erik Smith

You need a later version of ArcGIS Pro.

Thanks, my organization has not approved any higher versions. Are there any older ArcSWAT executables, or do I just need to wait until my organization catches up.

Thanks,
Erik

One last question, if there are not any older ArcSWAT executables available, is it version ArcGIS Pro 3.4.2 that I would need?

Erik:

If you haven’t already done so, click on the link below and go to the bottom of the page under:

Archive: ArcSWAT for ArcGIS-ArcView Extension

Here you can choose the ArcGIS version and download the version of the SWAT model.

https://swat.tamu.edu/software/arcswat/

I hope this helps.

Thanks, I did see that for previous versions, but those are all for ArcGIS Desktop (ArcMap) which is going away. I was mainly wondering if there were any ArcSWAT modules built for ArcGIS Pro older than version 3.4.2. Thanks!
