How to install a service pack for Policy Studio and Configuration Studio
Problem
The service pack READMEs for 7.2 and 7.3 Service Packs state that the Policy Studio / Configuration Studio component should be deleted and re-installed from the base product bundle. This is incorrect and the patch file archive can be used to overwrite files in the existing installation.
Resolution
A better approach for installing a service pack with Policy Studio and Configuration Studio would be:-
1. Stop Policy Studio / Configuration Studio
2. Backup the previous version
3. Unzip the patch bundle to the installation directory (Windows) or "tar -zxvf patch-file.tar.gz -C installation-path" (Linux / Solaris)
