I try to customize my form. I created a new property and I try to Edit the design. I restarted the application and activated my package according the instructions. But the menu item “Customize form as …” is deactivated (not accessible). I can click only on “Customize form”. It mean I’m not able to store my settings to my package. As well as the button “Save Form to” isn’t accessible. I can click only on “Save Form”.
Select Settings menu | Options | Expert Mode and clear checkbox Save the Definitions to the ‘My Package’. Then you can define where you want to save the changes - to an add-on etc.
