Unfortunately this did not solve the problem for me
I am trying to connect Olympus Pen F camera to W10 Pro 64bit
With the MDF driver installed the camera is recognised by the Device Manager
but not correctly by the Olympus Viewer 3 sw.
In particular by the Firmware update function
Olympus blame W10, but I suspect an incompatibility with their SW
I do admit that the Olympus Viewer works with W10 32 bit and even W8.1
but that is not much good to me. :-(
Any ideas are most welcome
