To create a virtual directory in your web server, use the Internet Services manager. Within the Internet Services Manager console, right click on Default Web Site and select the New, Virtual Directory option. This will open the Virtual Directory Creation Wizard and you can follow the steps to create a virtual directory. Point the virtual directory to the folder where you have your application deployed on the server.
Other reasons why you might get this error include:
Your application’s Bin folder is missing or the application’s DLL file is missing.

To deploy your application to Webroot, follow the instructions in Deploying to Webroot.
