I've a setup that is working now for a couple of years under different target environments. Now the same setup fails to complete under Windows Server 2019. It displays an error message "Library not registerd" in the moment when it should display a progress dialog that contains a Flash movie. The setup itself is not missing any files, because the same setup works on a different target system without problems.
We could reproduce this behaviour in a virtual machine with a fresh installation of Windows Server 2019 in our office.
I've re-compiled the setup with the current version of InstallAware X10, but the problem still exists.
If I remove the FlashFrame, the setup is working again, but that is obviously no solution.
The manual states
The moment a dialog containing the FlashFrame control is shown, InstallAware will automatically attempt to install the player runtime if it is not already available. If the installation fails, the dialog will not render the movie, but no setup error will occur - your installation will continue normally.
But this is obviously not the case. The setup terminates after the error message.
Could you please check that and provide a fix?
