Hi,
Thanks for the support in downloading ArcSWAT 2012.10_8.25. I downloaded ArcSWAT 2012.10_8.25 but faced another issue while installing it. I have installed ArcGIS Desktop 10.8 version 10.7.0.10450 but got the error while installing ArcSWAT: "ArcGIS Desktop 10.8x is required before you can complete this setup." After pressing OK, a new window opens with the following message.
"The installer was interrupted before ArcSWAT could be installed. You need to restart the installer to try again"/
