Just recently performed upgrade to Confluence 4.3.3. Running via startup.bat works with no problem.
Install windows service via command service.bat install Confluence and install runs without an error.
Tried starting the created Confluence service, but it does not work, it comes up with this error below
Windows could not start the Apache Tomcat Confluence on Local Computer. For more information, review the System Event log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 0.
