Installation throws error 0x000005b3

[Tony]

I am an admin on my Windows Vista Business (Build 6001 SP1) AND I am running the Bullzip setup exe as 'Run as administrator'

After 99% of the installation, at step 'Creating printer...(can take more than a minute)', I get a messagebox titled: 'Printers'
containing the text: 'Operation could not be completed (error 0x000005b3)'

I have an HP CX11N printer available to my Vista as a networked printer and the install log seems to point to the drivers for it as possibly causing the problem (the file HPEACLHN.HPI exists and I can read/edit it ok)- othe rdriver files from/to the same directories didn't fail. HOWEVER, when I try again, it is a slightly different HP file that fails - I'm baffled!

Looking at the installation log, I see at the end:
