Search for this file Microsoft.Office.Interop.Excel.dll and copy it in GAC. That should solve the problem.

This article should help you copying it.
The tool Gacutil.exe comes with .net framework.

thanks for the input, however, this is beyond my skills, do you know of a repair  I can download and execute automatically?  I do not know how to access the .net framework tool.

It's easy actually.

Let us first determine if the assembly is actually present on your machine or not.

Open C:\windows\assembly or %windir%/assembly folder and locate the file entry


Let me know if you are able to find it there. If it is not there, I'll write another set of instructions on how you can install it.
If you locate it, please share a screen shot. This will show me the version and other information about the assembly.
here is screen shot - file found  Keep in mind that I am using Windows 10
