I've been trying to get a virtualized copy of Firefox setup as a first class citizen on my Win7 boxes. On a clean Win7 VM if IE has never been run, none of the UserChoice reg keys have been added and as such the "default" keys added by my package allow Firefox to be seen as the default browser for http, https, .html, htm, etc. In other words everything works perfectly as though the browser was natively installed.
The problem comes when IE is launched (or other native browser) and sets itself as default. At this point the Firefox package has no way of overwriting those defaults, even during a re-register or uninstall re-install. This is due to the priority given to UserChoice keys in the registry heirarchy. I've tried adding them to the HKEY_CURRENT_USER reg file, but that has been unsuccessful. In a previous thread I noted a passing comment about registry hacks that allow packages like Firefox, Thunderbird and others to be registered as valid default programs. Unfortunately I have been unable to replicate this functionality.
Is there a way to get ThinApp'd packages to be seen as user selected default programs... or at the very minimum reset default choices during a re-register or reinstall? If so, how is this done?
