iTunes - Desktop Central Patch update

Hi All,

Environment:

2008 Domain controller
Windows 7 x64
Software Restriction policies enabled (prevent execution from root directory)
Windows 7 UAC Enabled.

Software: Apple iTunes x64
Latest Update: iTunes X64 (11.1.2)

Problem:

Error on startup saying a particular DLL is not registered after applying updates automatically from Desktop Central.

Resolution:
Manually uninstall and re-install from each client PC after entering admin credentials. (Painful)

I know this error is related to Apple, Itunes & Microsoft but I'm hoping is there anything I can do in Desktop Central to alter the deployment to avoid this error occurring again? I'd appreciate any feedback :)

Thanks,

Sam.
