we are evaluating the iprint 1.1 appliance...

Predominantly Win7 Pro SP1 x86 environment, but interested in mobile too.

When trying to install a Win7 32bit printer and get
"Printer ... failed to install.The remote procedure call failed"

RPC service looks to be running OK, as does Print Spooler.

From Application Event log is see corresponding error:

Faulting application name: PrintIsolationHost.exe, version: 6.1.7600.16385, time stamp: 0x4a5bcebc

Could this be particular to this driver or is there something more generic I should be looking at?
