I have 2 scripts using the /V feature. One is a test script, which works. The other is a production script, which doesnt.

The command line looks like this:

SetupFileName.EXE /S /Q /V _PAC_ "A long string of gibberish with no embedded spaces"

Working script:

Name:  SBImage1.jpg

Size:  76.4 KB

"Working" means the message displays the value included on the command line after the /V _PAC_ "ie, this value"

Not working script:

Name:  SBImage2.jpg

Is there something about the DLL call that requires we do something differently?

When the not-working script is run, the DLL displays a window, even when /V _PAC_ "stuff" is used.
