Office 2003 Pro - Cannot print from Powerpoint

Hi - Not sure what I'm doing wrong here...

Using ThinApp 4.0.0-2200 to capture Office 2003 Pro via a clean XP Pro VM

Captures fine, builds fine & works a treat EXCEPT - trying to print from Powerpoint generates a "No printers are installed. To install a printer : ...." (see attached screengrab)

All the other Office 2003 programs (Access, Excel, Publisher & Word) can print fine using locally installed printers.

I've tried re-capturing via a clean 2000 Pro VM, with the same result.

I've also sucessfully captured Office 97 Pro and Office 2000 Pro in exactly the same way and they all work perfectly. Whats different about printing from Powerpoint 2003?

Any suggestions.

cheers

Dominic
