Script Debugger 7’s Enhanced Applets include the Sparkle software update framework. This document describes how to configure an enhanced applet to update itself using the Sparkle software update framework.
If the Enhanced Applet shell detects the absence of these settings, it will disable the Check For Updates menu item. If you feel you’ve done everything these instructions call be, you can email me a copy of your applet and I’ll check into the problem for you.
I’ve replied to @Tekl privately on this, but the answer bears repeating here. There is a bug in Script Debugger’s enhanced applet shell that prevents the Check For Updates command from being enabled. This will be corrected in the upcoming Script Debugger 7.0.5 maintenance release.
