Hi again :o)
Thanks to MerijnB, I've registered a file extension which executes my application.
This works great BUT I need to go a bit further...
Now that I've got to create a link on a HTML page that links a file with my new extension, this I've done but when I click on the html link it doesn't execute it so my application is not opening.
Just link when you click on a link .pdf or .doc etc...it opens the application associated with it.
I created a html file to test it but it won't work:
<title>Execute my Application Bla</title>
<a href="test.vra">Launch My App</a>
