Install NS 7.5 with batch file?

I have my NS server setup with https and for this example I'll use NS75.company.org as my server name.

This is what I have been trying to use and it isn't working. First it makes a directory and copies the needed files.  Second uninstalls 7.1 and waits 5 minutes.  Then installs 7.5.  The only part not working is the install.  It kind of works sometimes in that the agent will be installed but it will never register with the server.  Should the /nsweb be https?  Any help would be appreciated.
