Manual Installing of NPPE

Hey,
i have Noteperformer 4.5.1 and I’d like to use NPPE….
I got a trial version of the playback engine

So I followed the instructions on the Noteperformer link to get the none-trial engine.
I got these files:
How and where do I install one of the engines please?

Unfortunately they are no longer available for purchase. I’m surprised you were able to get a trial version.

the trial version of every library is automatically included in NPPE. The main problem is that audio export is disabled, otherwise the trial versions would be quite useable.
