Leaving IE alone as it works, I would firstly ask why you would need so many browsers installed?
I have only ever heard of folk using their browser of choice, in your case IE, and having a backup browser in case of an emergency. However I understand it is your choice, so let us see if we can get at least one other working for you by doing the following.
- Download and install Revo uninstaller to your desktop
- Run it, follow the prompts to uninstall each of the non working browsers one by one
- Reboot your computer
Choose one of the three to download and install making sure you do not choose added tool bars or anything other than the required browser offered. After installation of the chosen browser, run it, go to the Help
tab, scroll to Check for Updates
to make sure you have the latest version.
My alternate browser is IE 8.0, but for everyday use I have CometBird
which I can highly recommend to you as a working browser of some standing.
Please read about Revo
on the link offered so you have a working knowledge why I am suggesting you use it instead of your Add and Remove applet.
Let me know how you proceed.
