[SOLVED] "Attaching the Script debugger to process iexplore.exe failed" message after upgrading to Internet Explorer 10

HUGE thanks going out to Dmitri Leonov - MSFT in a stackoverflow article about the same message.
After updating to Internet Explorer 10, I started receiving the error when debugging with Visual Studio 2010:

"Attaching the Script debugger to process [####] iexplore.exe failed.  Another debugger may already be attached to the process."

The fix:

  • Close all instances of Internet Explorer.  (I will add you can leave Visual Studio open)
  • Run a command prompt as Administrator and paste this little gem into the command line:

It worked like a champ for me (and apparently others from comments on the stackoverflow post.)

Good riddance to an annoying message!  Happy coding.
