Change Registry Key Setting?

[Jennifer_Hayes]

I have PS script (that works locally) to change the registry key that enables/disables the windows firewall. I'm unable to get it to work via the installer and I'm not sure how to create custom actions yet (very new here).
Am I making this harder than it has to be?

Thanks! I did get a reg key change script with just a regular "Add Key" function to work (forcing overwrite.)
I was, in fact, making this particular task too difficult!

PS scripts can be a bit tricky in the deployment because you can't just run them as a script in a deployment package. It it better to run them as a command to make sure no execution policy is stopping the script.
