Is there any way to get a file transfer from an Olympus OM-D EM1 Mark II to Windows XP? As far as I can tell, the only way to get files off the camera is with Olympus Viewer 3 which does not work on XP. Viewer 2, which does work on XP, does not appear to be able to communicate with the camera.
I run Olympus Viewer 3 version 1.5 on XP, Olympus UK shows that XP is unsupported after v1.5, the next being v2.0 released 01/27/16.
Trouble is I can't see anywhere to download it anymore. It's worth checking around as I've noticed in the past that the various Olympus sites around the world often have different content.
I don't know how I got hold of it, or if v1.5 will support your camera. I'm guessing not as the mark II came out in 2016. The only thing I can suggest is using an old installation disk to load up an earlier version and (if necessary) then using the software's update service.
