Hi Chia Cheah Shen,
Thank you for posting in MSDN forum!
As far as I know, the .NET Framework 4.7.2 is a component of Windows. If you have a valid EULA for your Windows,
you could usage and install the .NET Framework freely.
About more information of EULA, please refer to this link:
Microsoft .NET Framework Redistributable EULA.
Hope my solution can help you.
Best Regards,
