"HTTP Error 404.2 - Not Found" error when running the app

When you run the application which is hosted in the IIS Web server, you get the following error:

HTTP Error 404.2 - Not Found
The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server.

Cause:

The IIS server settings block the download of the CloudAppLauncher_Installer.exe file.

Solution:

In the IIS Manager, expand the server's node and then the Sites node in the Connections panel, select the website where the application is hosted, and then double click Handler Mappings on the Features View, and set CGI-exe to Disabled.
