Hello Peter,

Thanks for your reply.

I checked my PC and found a folder named C:\Programfiles(X86)\Common Files\VST3\SSL\ containing VST3 files with extention .VST3 and I wonder if files of type .VST3 can also occur with extention .dll?

In the meantime I got a little test-app from jbridge which supplies information of a VST when loaded. For test I checked a VST from my Sonar VS DAW called Sonar VX64 Vocalstrip.dll, which is a 64 bit VST. It loads succesfully in my DAW and offers an interface.
When I run the 64 bit testapp it tells me this is a VST 2.x plugin type, so now we are sure its not a VST3, right? When I load the plugin in BIAB 2015 with jBridge installed nothing happens, no interface appears. Shoudnt this VST work in BIAB?

greetings
