FileMaker server 15 to 16 upgrade

[Agentshevy]

Problem Upgrading to Filemaker Server 16.. We want to Upgrade from FMS 15 to 16, and each time I get this error during deployment.

However, when I revert back to fms15, everything goes fine.. I have tried Clean Installation, yet same result..

Can someone put me through.. We are using Windows 7 professional as our system unit

that's not a supported OS.
