ARCHICAD Update cannot access one or more files

by Márta Trón · updated: 03.14.2017

Affected version(s): ARCHICAD 20 | Severity: workaround applicable | The issue is only present on OS X


When running ARCHICAD Update installer the user gets this error: “ARCHICAD 20 Update (xxxx) cannot access one or more files/folders in …”



It is possible that for some reason the user permissions have changed for the installed ARCHICAD folder. For example: It can happen that after restoring the Time Machine backup to the new computer the user has lost ownership over the ARCHICAD folder.


Duplicating the installed ARCHICAD folder and erasing the old one should fix this problem.
Updating the permissions to the ARCHICAD 20 folder should also fix the problem.
