HI There is no automatic update available. What i do: If you have UnIServer on C:\ 1.) Unpack the new version to C:\NEW_UniServer 2.) Copy the content of C:\UniServer\www to C:\NEW_UniServer\www (<-- clear it first) 3.) Stop and uninstall all UniServer-services 4.) Copy all your custom database-folders AND the folder mysql from C:\UniServer\usr\local\mysql\data to C:\NEW_UniServer\usr\local\mysql\data (overwrite yes) 5.) rename C:\UniServer to C:\OLD_UniServer 6.) rename C:\NEW_UniServer to C:\UniServer 7.) start the Start_as_service.exe and install the sevices and turn it on. finish. Has worked everytime for me. Maybe not the best-practice, but... it works.
