Where can I download Data Protector 6.2 for Windows 2003 or 2008 server?
You have two options.
1. SSO portal / http://support.openview.hp.com/software_updates.jsp
2. Trial download on http://www.hp.com/go/dataprotector
Remember that you should apply current patches to a fresh installation. This is true for client and cell server installation. This requires patches to be downloaded from SSO portal. (requires SAID)
