Desktop Application Launch from Chrome

There is a requirement to launch desktop application from chrome.we have created our own custom chrome extn to serve this purpose.

There is functionality in our application where desktop application has to be launched from web application with dynamic parameters . This functionality we were able to achieve in IE by using microsoft internet browser object [ activeX object ]. This was not working in chrome. To achieve this we have created custom extension. So On click of a button in web application , custom event will be triggered and content script listener listens to the event and communication is established in background script.And the desktop application will be launched. We want this extn to be installed in all discover agents to be able to launch dispute application (which is desktop application).
