Add Scrip Map error in IIS 7

Error:

The specified module required by this handler is not in the modules list. If you are adding a script map handler mapping, the IsapiModule or the CgiModule must be in the modules list.

Background:

I had this error message when configuring BTSHTTPReceive.dll into Handler Mappings  of IIS 7 in my development machine.

Solution:

Windows 7 64 bit:

1. Go to the “Control Pannel” –> “Programs and Features”
2. Click on “Turn Windows features on or off”
3. Make sure “Application Development Features” are enabled.
