$cmdline = %comspec%
$cmdline = $cmdline + " CreateZimbraProfile.exe ZimbraProfile mail.server.com 443 1 " + @USERID + $pwd
Shell $cmdline

The exe is inside the kix32 folder.

When I run this I prompt the user to put in the password
AT (15,25) "Password : "
$pwd = AT (15,40) Gets $pwd

when it runs the $cmdline it changes my display and shows the what the command line would C:/Documents and Settings etc.
