Thank you for your feedback! We appreciate your interest in AVS4YOU software.
Let us briefly answer your questions:
Use system window frame (recommended)
This option affects the applications’ GUI: check this option to display the interface for window’s frame rectangle in AVS applications in accordance with Windows system settings.
Or you can uncheck it and use the native frame for AVS applications.
Yes, there is nothing called “Activate” in the Help menu.
The important point there is if the AVS applications are activated on your PC or not. If yes, there won’t be any offers to activate the software again.
Otherwise, you can activate the software in different ways: in the Help tab of the program or via Windows Start menu > AVS4YOU > Activation
A “Script error” pops up while trying to read the built-in help, not a good sign.
Your issue will be forwarded to our developers. At the moment, we recommend you to use Online HelpCenter, available on the official website http://www.avs4you.com (Help page)
For any details, we recommend you to contact us at firstname.lastname@example.org. Our managers will be glad to help you to resolve your issues as soon as possible.
