quickbooks 2017 enterprise on windows server 2016 fail to turn on .net framework 4.6 feature

upon installing QB2017 Enterprise on windows server 20146, QB Database Manager will crash when scanning folders, here is what I can manage to find out.

QB diagnostic:

 fail to turn on .net framework 4.6 feature 

I turn on all framework 4.6 feature using "add feature/role", the error still persist.

I get the following error event
