Hi Keith,
I moved this to the forum as I believe other might have this problem as well. I hope you don't mind.
If you get the message: "Sorry, an error has occurred. This application cannot be installed because this installer has been misconfigured. Please contact the application author for assistance." it is in most cases because the previous version of the Production Tool hasn't been deleted, please delete the previous version of Production Tool before installing the newer version.
Another problem would be that you don't have the latest version of Adobe Air installed: http://get.adobe.com/air/
Let me know if this didn't help!
