Microsoft JScript runtime error when using "Use Local IIS Web Server"

Question

Everything was working fine until someone in a Microsoft forum had try a couple devenv switches in command prompt mode: devenv /Resetsettings and Run devenv /ResetSkipPkgs.Prompt for an unrelated problem, namely that I could not save aspx files with one click of the save button. Ever since then, I am running into a new problem.

I tried uninstalling VS2012, rebooting, and reinstalling to no avail.

The problem is that I receive a Microsoft JScript runtime error when using the "Use Local IIS Web Server" setting. IIS cannot find variables defined in files it loaded. When I run with the "Use Visual Studio Development Server" option, then it works.

Why is that and how can I get the "Use Local IIS Web Server" working again.

2 images showing the problem.

(I uploaded the images yesterday, not sure what happened.)

I am not sure what to make of the problem. I saw another post on a different forum regarding a similar issue.

0x800a1391 Error Codes are caused in one way or another by misconfigured system files in your windows operating system.

The 0x800a1391 error may be caused by windows system files damage. There can be many events which may have resulted in the system files errors. An incomplete installation, an incomplete uninstall, improper deletion of applications or hardware.

I would sincerely say that you should either restore your computer to an earlier time before you had played with devenv switches. They did nothing but corrupt you system files and created a bug inside to halt the program from retrieving data for javascript code to execute.
