Our MBS FileMaker Plugin in version 10.5 added newer WindowsML functions for Machine Learning on Windows 10.
Adding those did break compatibility to Windows 7 by referencing newer functions introduced in Windows 8.
If you need Windows 7 or as server Windows Server 2008 R2 support, please get the plugin here:
As those Windows versions are unsupported, nobody should use or need them anymore.
In future, we may only provide Windows 7 compatibly plugins on request as current FileMaker Pro doesn't even run on Windows 7 anymore.
