This guide instructs how to upgrade H-Sphere Windows software from 2.3.1, 2.3.2, 2.4 Betas, RC 1, 2.4 Final and 2.4 Patches 1 and 2 to 2.4 Patch 3.

Requirements:

1. Make sure your H-Sphere Windows module has version 2.3.1 or higher:
   Open the file [Disk]:\\HSphere\scripts\consts.inc and check the parameters:
   // the current version
   version = 2.31
   If the version is older, update it to version 2.3.1 or higher.
2. Open SOAP port 10125 for data communication between Control Panel and Windows server.
