Initializing the applicationhost.config file failed. Cannot find IIS Express

I recently installed the Visual Studio 2017 RC and created AngularJS SPA application. I had to uninstall the VS 2017 RC as it was hanging multiple times. Now, Whenever I try to open this SPA application using VS 2015 I get this error. Any help to resolve this would be helpful. Thank you.

Where is ApplicationHost config IIS Express?

Configure IIS express on visual studiovs folder (Hidden) -> Config -> applicationhost.

How do I get IIS Express in Visual Studio 2019?

For the ASP.NET and web development workload, locate and install the Development time IIS support component.

I have got the same issue. So I install the IIS Express from https://www.microsoft.com/en-us/download/details.aspx?id=48264
