"Zebra CoreScanner Driver (64bit)" -s -f1"zebradriversetup.iss"
When I run this from C:\Windows\systems32.cmd.exe it works just fine. When I tried to build an MSI with it in the prerequisite section, it does not work. I think I've finally figured out that it is launching PowerShell instead. Trying the above command in PS does not work manually.
So how do I fix this?
