I am trying to get the client installed using ZEN but an unable to get
the installation silent. We are using ZfD 6.5 sp1a on a Windows XP sp2
platform. Using the following command line:

Setupnw.exe /ACU /D:no /U:c:\admin\nwclnt491sp2\admin\unattend.txt
/SL:c:\admin\nwclnt491sp2_log.txt

My setupapi.log file has these errors

When I looked up the 0xe000022f error I found TID 10093007, do you know
if there is a fix besides running this object as an unsecured system
user because running it as an unsecured system user does not allow me to
make the installation completely silent?
