Hello Adam,
it seems like they wont support Windows 2003, 2008 32 bit anymore:
"Unfortunately Windows server 2003 is out of support for a long time both by HPE Data protector and Microsoft. About this failing upgrades we cannot assist any further. If Windows sever 2008 are 32 bit we can also not give any further assistance because they are not supported either by HPE Data protector."
Bute they're gonna check my Windows 2008 64 bit non R2 systems. Let's see what happens.
Kind regards
Guido
