I have no problems what so ever, so it might be a bug, but maybe the staff would like your savegame, and you fmrte error log. You can upload it to a server, and then put the link for the files in here..., a place like filedropper, or something like that.
I have now tried to install the recently downloaded FMRTE version 16.2.0 (build 17) but I am still told that it is not compatible. However, I think that I might have discovered why. I am a Microsoft Windows Insider running Windows 10 Pro 64 bit version 1511 build 10586.36 so I wondered whether there were issues with this restricted released operating system. I have another PC running the officially released Windows 10 Pro 64 bit version 10240 so I tried to instal FMRTE on that machine. I am delighted to report that it did run. It would appear that version 1511 is the cause of the problem.
