I have a user with a MacOS Sierra 10.12.3 which previously had A21 installed on his desktop. My colleague removed the 21 version (he still has 19 and 22) to reinstall it. He also removed the prefs.
The host has about 700GB of free space
When we try to reinstall we receive a message about the path being wrong (Apps:Graphisoft) and the available space being 0.
We have tried to change the path, check access right to the path with no result.
