While upgrading the Sitecore Module to version 1.4.1, a client reported this error:
ERROR Installation failed: System.Exception: Background process failed: Access to the path is denied. ---> System.UnauthorizedAccessException: Access to the path is denied.
This issue can sometimes occur when the Sitecore AppPool doesn’t have proper permissions. Make sure that the AppPool has write/admin access to the Sitecore root directory.
