I've had this issue over and over and over and the advanced installer really isn't a working application that just works, its really hit and miss.
I added the trial to the application, the only thing I have chosen is Expiration Date.
Application is installed, it then pops up and says Expired.
Even though the application is run in admin and you right click and choose " Remove Trial Info" >> This process doesn't actually do anything.
So anyway its expired.
Click Generate Registration Keys
Enter new date for 6+ months or 2020.
New key is generated, copy and paste that info into the trial box.
The registration key is invalid.
This is where Advanced Installer really starts to fail. There really isn't anything you can do beyond here.
Quite disappointing.
