Installing php_zmq zeromq on XAMPP with PHP 5.6 as a service

I have tried quite a few things like newer Xampp and see if works on Win10

I get it to work on Windows 10 with Xampp 5.6.30 and php_zmq-1.1.2-5.6-ts-vc11-x86
but the same setup on Server 2012 r2 Std gives the following message:

PHP Warning: PHP Startup: zmq: Unable to initialize module
Module compiled with module API=20121212
PHP compiled with module API=20131226
These options need to match
in Unknown on line 0

Regarding either version Xampp I tried, my Windows 10 machine has the following VC:

Not sure I am missing any, unless there is a specific version needed - but then why isn’t that posted on the PECL download site.
