Installing using a script not working

I installed webMethods 6 successfully and recorded a script. When I try to use the script I get an error saying we’re not authorized. It seems to pop up at a Broker panel, but I’m not installing Broker, just the JVM under Broker required for the Integration Server. This is a panel that comes up when the script runs, but doesn’t come up when I install it manually.

I’ve even tried using no serial number. When I do use the serial number and check the script, it is in there correctly.

Why does it work when I do it manually, yet not work when I run the script? A script sure would be a lot easier since I have a lot of checking and unchecking to do on the installation!

Any help would be GREATLY appreciated!
