Errors installing Arcswat for Arcmap 10.8

[Etienne Delaloye]

Hello everyone,

I'm a student at University of Lausanne and I'm trying to install the Arcswat plugin to use with my Arcmap 10.8.1 provided through my university licensing manager.

Unfortunately, an error message called 'Error 1001' pops up as follows:

 Error 1001. Cannot get the types of installers in assembly C:\SWAT\ArcSWAT\SWAT_HRUs.dll->cannot load one or more of the required types. Extract the LoaderExceptions property for more information.

However, I've made sure I had all the prerequisites in the readme.txt but I cannot know why it won't install...

Is it because I've got a SWAT+ extension installed running on QGIS? If you have a clue, let me know !!

Thanks for your feedback

Etienne
