I am having issues using TauDEM. The official website (http://hydrology.usu.edu/taudem/) is offline. I managed to find an installer on another site, but I get an error when I try to launch any function in ArcGIS, and despite installing the various tools suggested in the forums I visited I could not solve the issue. I always get an Error 000732 related to the output file and to CalculateStatistics. See print screen:
I feel that just being able to access the proper files could solve this, but I don't know how.
