First of all this is not a installer (like Newgen)! So you will have to put the map
(Unpack) from the zip file on your hard drive.
After that you start the Mosaic file, now you will see that it stores your changes, if you run it straight from the zip
file storing the changes wont be possible!
And second Mosaic will not autostart after a clean boot! Just put the Mosaic.exe file in your windows startup folder.
After you got everything running you might notice that the tiles snap back or placed randomly on the grid,
to get rid of this bug use this fix:
Unpack it in your Mosaic map on your hard drive.
