Download the full, off-line installer from here, and save it. https://www.mozilla.com/en-US/firefox/all.html

Then double-click the EXE file to start the installation.

Trying to install Firefox in Windows 7 Home Premium on an HP Pavilion PC. Download works, but when I click run, nothing happens. I have tried installing in both IE and Chrome and still nothing. Any ideas? I think it may have something to do with how my user account is set up, but don't know enough about setting up accounts to investigate further. I am a 68 year old grandmother of 6 who is not all that technically savvy so any advise has to be step by step or easy to understand. Thank you. Sandra in McLean, Virginia

I made it a bit further. It extracted the files and then when I clicked run it asked me if I wanted to run it as administrator or current user. Since I don't know anything about administrator, I chose current user. When I clicked on current user, nothing happened. It failed to run again. I guess I just don't understand user accounts and what they do. I also tried running as administrator, but it wanted a password and I have no idea what it might be.

Did you Download the full Firefox installer and save the file to the desktop?

The small stub installer that is offered by default needs to access internet to download the files and can be blocked by security software causing the download to fail. The full installer shouldn't give this issue.

Try this:

• Download the full Firefox installer and save the file to the desktop
  https://www.mozilla.org/en-US/firefox/all/
• Start the installation with a double-click on the desktop icon

You should get the usual UAC pop-up from Windows to start the installation.

I resolved the problem on my own. I ran a compatibility check and it resolved the issues I was having with the executable and I was able to install Firefox successfully. Thank you all for your help. Sandra
