Okay, after going through the forums, I think I can accomplish an "unlimited" trial by following the directions posted here:
http://www.advancedinstaller.com/forums ... =2&t=21295
This way, I can use the
"ReadSettingsRetStr" property and activate all features if it returns 0, and disable the premium features if it returns anything other than 0.
From there, if the user ever decides to register the product, I can just use the
"DisplayRegistrationStr" property or use a custom dialog to perform registration.
Please let me know if this is a valid use case.
