Hi, I'm using Drone2Map 1.3.1 and I'm facing the same issue. the software crashes as soon as it opened. I installed "Microsoft Visual C++ 2008 Redistributable - x64 9.0.30729.6161", but the issue still there.
We recently determined that Drone2Map will crash in certain circumstances if it is installed after ArcGIS Pro. Try this: Leave Drone2Map installed, remove ArcGIS Pro and reinstall. You may also want to try starting Drone2Map in between (after removing ArcGIS Pro).
