Answer 1

You cannot run applications from a website on client's machine due to security & permissions.

However, your website probably can communicate with the scanner. Check this detailed answer .

Answer 2

While you cannot run the application from the browser, there is another option, if your application is already running in the background. Then you can make it listen to some local port and then ask the browser to redirect to the URL (consisting of localhost and that port, eg http://localhost:34554 ), so the application would receive an HTTP request and will know it needs to become active / show its window / etc. Using this technique, you could even pass some parameters to your application using query params in the URL.

Another option that allows you kinda run an application from the browser is Microsoft ClickOnce - it is just a simplified way of installing and running an application without the need for the user to download and manually run the installer.
