processing error - really wierd

PIX4Dmapper PIX4Dmapper Questions/Troubleshooting
1

Working on my first project and I am getting a processing error.  80 images collected with a Phantom 4 (latest firmware). When I go to process in Pix4dmapper it won’t process.(ver 2.1.53 64bit).

the images are of farm fields, forest, few buildings.

The log file says it can’t write to the C drive and then says “no error”

Any ideas - log below
