Unfortunately, I couldn't find an installer for Everio MediaBrowser HD Edition on any official sources. Furthermore, according to its website, the application hasn't been updated in a long while and it won't work on 64-bits operating systems, so that might turn out to be a problem even if you do manage to find a downloadable version.
The only advice that I can give you is to contact the company directly and see if their people can help, but the only way you could do that seems to be via phone:
- +1-866-749-3521 for North America;
- +1-416-447-9456 for the rest of the world.
