This guide will show you how to enable a browser link that starts your custom application.
I needed this functionality to enable my users to start a windows application I buildt from a browser or email.

Example:
When a user clicks the link <a href="applink://documentid=3343">Open document<a/>
I what to open my application with the parameter: documentid=3343
Similar to executing: C:\Program Files (x86)\Gaudio\Gaudio Impuls\impuls.exe document=3343

How to do it:
All you have to do is make a few registry keys, and you are good to go.

Parameters
Name of the link applink
Application location C:\Program Files (x86)\Gaudio\Gaudio Impuls\impuls.exe

Create the following registry keys
HKEY_CLASSES_ROOT\applink
HKEY_CLASSES_ROOT\applink\DefaultIcon
HKEY_CLASSES_ROOT\applink\shell
HKEY_CLASSES_ROOT\applink\shell\open
HKEY_CLASSES_ROOT\applink\shell\open\command

Create the following registry values
