I am confused!
Above you mention that AF 1.5 Compatibility Layer is included. However on the support website version 22.214.171.1245 is available.
I thought this pack contained the latest software.
In fact the pack contains AFCompatibilityLayer_126.96.36.1995.msi - so it is the latest version.
As Andreas pointed out, the Compatibility Layer we provide in the vCampus PI Products Kit is indeed the latest one: 188.8.131.525. When I first wrote Compatibility Layer 1.5, I was referring to the Assemblies that make the AF 1.x to 2.x communication possible: they are versioned 1.5 because they are the intermediate between 1.x and 2.x components.
The screenshot below (click to enlarge) shows the difference between the .dll files as installed in \PIPC\AF\PublicAssemblies (v184.108.40.2065 and 1.x) and these same files when registered as Assemblies in the GAC (v1.5, for those assemblies into which 1.x/2.x interoperability is required):
Sorry for the confusion (and for the delay clarifying my original thoughts on this )!
