Has anyone else had problems getting Mosaic or Mosaic to new Raster tools to work in an ArcGIS Pro Add-in? I have an add-in that searches folders for rasters, the mosaics the found rasters. The Add-in works fine on my Windows 7 machine, but the mosaic fails on Windows 10 machines. I have tried both Mosaic and Mosaic to new Raster, and both have the same results. I have had the same problems in python scripts. Running the Mosaic and Mosaic to new Raster as geoprocessing tools from the toolbox works in Windows 10, it only fails when it is in a script or add-in.
