Unable to initialise package information (0x000000). Is this because I'm using the Trial Version?
No limitations should be present while in trial period, we only insert some messages in your package, telling you the package was created with the trial version.
Probably something was not imported correctly. Please note that after importing some editing is required for the packages to work correctly.
Regarding the improvements, I've passed them to my colleagues from development, hopefully they can add them to Advanced Installer
as soon as possible.
