I am facing an error with .Net Framework while running my VSTO excel addin application. The error screen shot is below. I am confused why I am getting this error even though .Net frame work is installed in my machine.

I think manifest files are missing in my machine but don't know how to check and how re-install.

"application requires that the .NET Framework be installed. Contact your administrator for the further assistance in downloading and installing it."

What I have tried:

I have re installed .NET framework

The .NET framework comes in several versions - 13 of them to date, not including Core versions: .NET Framework version history[^]
So start by look at what version(s) are installed: How to: Determine which .NET Framework versions are installed | Microsoft Docs[^] and what version your code needs: Configuring a Computer to Develop Office Solutions[^]
