It installs just fine for me and have done so on a few machines now (all Windows machines).
But on one machine in particular it does something to the WIBUkey software and Archicad will no longer run - WIBUkey error.
It is fine straight after the install and works perfectly but won't run after the machine is restarted.
It also stops any other version from running.
I uninstalled 15 and the other versions worked again.
Re-installed 15 with no hotfix and all was fine (even after restart).
Installed hotfix 3 again and all was good until the machine was restarted.
So un-installed and re-installed 15 again and upgraded to hotfix 2 and all is fine again.
I won't bother with hotfix 3 on this machine.
At least I now know what it is if other users suddenly start not working.
Waiting for hotfix 4.
