Dear Branko,
there’s been a bit of confusion.
I guess the “OpenACS” you are interested in is
http://openacs.sourceforge.net/ and it has to do with Devices Management.
This one here is the Windows Port of another “OpenACS” (
https://www.openacs.org/).
These two pieces of software have in common only the name and the fact they are open source.
Ciao,
Maurizio
