Can you change ExecWait detail text?
I'm working on an installer that during the install executes another installer the command I use to do this is:
ExecWait '"msiexec" \i "$INSTDTIR\povwin.msi"'
But I would prefer the installer says: Launching POV-Ray installer...
Rather than: Execute: "msiexec" \i "C:\path\to\install\povwin.msi"
It's no big deal but the default is a bit ugly. :(
