Hi!
This issue was in previous build and now it does the same - removes downloaded installation package after successful installation process. It does despite of active option "Keep downloaded library data". I understand that executable installations are not "library data", but I remember that first versions of Vienna Assistant (maybe erroneously) kept downloaded installations as well as library data.
It would be nice to have an option "Keep downloaded packages" even these are library data or installations. Or second option to differentiate things - "Keep downloaded installations".
Some users (like me) have more than one computer in studio, but sometimes internet connection is slow. It's good to have installations downloaded once and stored in local media.
