And unable to use FxSound Enhancer. Even I launch this program, this message shows and close when I press [OK]

Hi,
May I ask which version you are running?
Support for all the legacy versions of FxSound has ended, and all license keys have become invalid.
So I would highly recommend visiting either fxsound.com or the Microsoft Store and downloading the new, improved, and forever free version, which should not require any registration at all.
Hope this helps; please let me know.
