The offline scanner has only been tested on Windows. As a Java app it should also run on other operating systems.
But there is one known limitation:
There is a known problem which I reported before on a Mac with step 4 which will be solved soon. I am not quite sure whether we see the same on other OS.
When you enter the filename with which the zip archive should be stored, the application will respond with 'Invalid filename'.
Please finish the scanner and zip the complete scanner directory instead of running through step 4
Do not restart the scanner - the restart will delete all old data!
