of course possible, but open the engine takes a long time. if you have e.g. 3 engine versions on your computer this can be pretty annoying.

As already said, that is just a usability thing, and far from beeing obligatory. It would just have been nice, if there was a way.

Ok, you can determine the edition from the key name. It works only for A8 though, key names had no relation to the edition with A7.

key8e or key8b -> extra
key8c -> commercial
key8 or key8p -> pro

Thanks a lot.
key8s --> free?

Just to give you an idea, what this feature is about: http://www.dev-software.com/public/LED/PublishProcess/PublishProcess.mp4

(only shameless advertising - no real relevance to the keys question )

Nice feature. I had to do a batch-file for this.
