MVHAUS  Just so you know

It installs an invisible folder (a dot before the name) called .install4j at the root of the folder where the program sits.

(for instance, the Applications folder if you chose it)

The folder contains a bunch of files like a log and .dll program files, and even a .exe Windows file.

Don't know what is this all for.

Invisible folder manually removed...
