Hi, I am trying to male Olympus Digital Camera Updater 1.2 update my Tamron 14-150mm Di III, which still has Firmware 1.1 installed, but on any of my PCs (running different versions of Windows7, 8 in both x86 and x64 flavors), this update fails: I successfully get to the point where the update is loaded to the camera, the two red circle signs on the camera's screen are flashing for a few seconds, and then instead of "OK" the camera says "NG" after only a few seconds. I have already replaced my Tamron with a new device of the same type, but the new one has exactly the same error. And this happens on several PCs, antivirus and firewall disabled. USB mode on my camera is set to "storage", I also tried "MTP", but this one does not work at all with Olympus Digital Camera Updater. So either my E-PL7 camera is defective, or this is a general problem. Any ideas how to fix this? Thanks for any suggestions.
