While my father was uninstalling firefox 6 he did not realize that he and my mother were logged in as users and had the application open. Firefox 6 uninstalled properly but left behind firefox 4 that will not uninstall. We have defrag the computer to make sure that the program was not seperated. He is logged in as the admin user. He has tried to download the new firefox 6 again but it will not install, I figure this is due to how he uninstalled with it open. Can you please point me in the right direction to correct this.

I assume that you have been to the Control Panel and checked Programs and Features that it is uninstalled.

Now open Internet Explorer and go into Internet settings, here make IE your default browser.IMPORTANT STEP, you need to reset the registry by doing this, if you don't you leave an invalid link to Firefox.

If you are willing to dump everything from Firefox you can go to c:/Windows/Program Files and delete the Mozilla Firefox folder, now go to your Start menu and open Run, here type %appdata% in the folder you will find the Mozilla folder, delete it. Firefox will now be gone from your computer, restart your computer and download and install Firefox.

Thank you but although we are using the admin account to do everything and have created a test admin login it is still not allowing me to just delete from c:/Program Files (x86). It keeps telling me that I need admin rights and all logins are admin....Is this more of a windows 7 issues?

If you are logged in as Administrator there is nothing you can't do to Windows.

If you are logged in as Administrator you will always get a warning then it will continue to a permission dialog box and you say yes, if you are not logged in as Administrator will be denied. Go to Control Panel then Users, there you can confirm you are Administrator.

I have verified that I am logged in as admin. It gives me the dialogue box and I click yes then it comes back with another dialogue box that says I don't have admin rights. I then created a test user account as an admin with a password and the same thing is happening. Do you think that if I delete all users except the first admin user that was created that I might get past this?

That would be my thought. Only an Administrator can change User accounts like that.

Deleting all users except the original, and a restart didn't work. Just gonna restore entire computer back to factory settings from the disc. Thanx so much for your help.

Ya I guess, sorry I couldn't think of any easier solution. It is a stumper, figuring it out would have been nice.

You are totally right but I just can't see what could be causing it and will only be here until the morning to help my parents with their computer. If I had the time I would keep at it until I figured it out.
