For all the people, who are still struggling to change your default browser to your choice, please google for 'fureteur4ppc', Out of the box, this program has most of the typical browsers to choose from, so that you can set them as default browser or you can paste the browser EXE file link, so that it will be set as default Browser.
The only draw back is, this software is not in English.
To setup custom browser as a default browser, launch the application and do the following.
1. Click on 'Tests blah blah' button, to check the installed browsers.
2.Click on the button saying 'Mon Choix' and enter your browser exe file path.
3. After that, click on 'Valider' button, to check the accuracy of the file path.
That should do the job. Soft Reset and test the default browser..
