IIS Error with "related configuration data for the page is invalid" on a newly Setup Machine

I recently got a new machine and installed IIS to run my Sitecore websites.

After getting SIM (Sitecore Instance Manager module) installed and quickly setup a new Sitecore 8.1 instance.

But, when try to browse the website, it returns following error message.

HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.

 

And, after referencing stackOverflow sites, saw that some of my Application Development features are not enabled.

 

 

 Enabling Internet Information Services -> World Wide Web Services -> Application Development Features -> ASP.NET 4.6 which fixed the issue.

 and now i am getting the following error, which was a huge release. 





Everyone knows how to fix this ;-)
