Thanks for clarifying. You have PFTW installation which you can run silently, but want to run in semi-silent mode.
What you can do is repackage your installation, making it a Windows Installer package. Then you install it using the MSIExec commandline. One of the parameters is /q, which sets the user interface level. Specifically, the parameter /qb will display only a basic UI. There are other UI levels available for the /q parameter as well.
Hope this is a little more help,
