Could not connect to service: ACL is not in canonical form and therefore cannot be modified. -
Description
The vRanger interface does not open and shows the following message in the event viewer:
vRanger Backup & Replication encountered an error during startup. The exact error message was: This access control list is not in canonical form and therefore cannot be modified. -
Cause
The issue occurs when the permissions are not ordered correctly in the vRanger installation directory or the Windows temporary folder.

Résolution
In order to fix the issue, we need to use Microsoft's Icacls tool from the command line. Please run the following commands to verify the ACL of the folders used by vRanger:
- icacls.exe "C:\Program Files\Quest" /verify /T /C /L /Q
- icacls.exe "C:\Windows\Temp" /verify /T /C /L /Q
If this verification fails for a specific folder with the message "Ace entries not in canonical order", you can reset the permissions on that folder with these commands:
- icacls.exe "C:\Program Files\Quest" /reset /T /C /L /Q
- icacls.exe "C:\Windows\Temp" /reset /T /C /L /Q
Once the permissions have been reset, use the installer to repair the vRanger Backup & Replication application and restart the server.
