Similar to another post. If you want FMI to support FMS then you will have to use a supported OS, which in this case is Windows 2012 R2. Windows 10 is not supported but I have successfully installed and being using on a test server. It would be a test you would have to do and you would be the one taking the risk.
Thanks, We don't use FMGO or any web services. It would be nice if they offered a version that would work with W2012 (albeit with some caveats) if they want to keep collecting my license fees.
Windows 2012 (non R2) was already on the list of deprecated features with FMS14.
So no fix is going to be made I'm pretty sure.
