Spooler SubSystem App Error on Driver Install

[jeffp]

We've had a few users report a Spooler SubSystem App error when installing your PDF Printer Driver (which we launch from out installer). I've attached some screen shots from one of our users who was running Windows 7 64bit.

I've actually seen it once or twice on my dev machine but then with the next install it goes away.

Have you seen this before? Any thoughts on what we can do here?

Below is a snippet of my commandline parameter that I pass to the driver exe. I use InnoSetup.

/VERYSILENT /NORESTART /COMPONENTS="pdfSaver,PDF-XChange driver" /DIR="%s" /PName="%s" "/Organization:FileCenter"

Jeff - this is your real command line? Including "%s" ?

Please provide information regarding the version of the driver you are trying to install and the specific exe as well - thanks

I using the PDFXSA_sm.exe downloaded from your site. The version is 4.0.191.0.

The "%s" in my commandline are repaced with variables. Sorry for that confusion.

Again, this a a very rare occurance, but has been reported a by a couple of users.

I will make some investigation to find where problem might be, but without the way to reproduce problem it is not easy to fix it.
It is also possible that problem causes by other printer drivers/print processors installed in the system.
