just downloaded 4.1.0.794 for trial (both 64 and 32 bit but not in parallel).
My first action was trying to connect my Nikon D850 camera. no chance :-(. I tried with SD card and w/o. different file types. I tried all this on a different PC with another D850->failed. I tried to connect my D800E-> failed too. Connected by USB.
For me no good starting poit for a promising software.
BTW: With BackyardNikon → no problem to connect.
Anyone reached to connect?
Thanks, Ralph
