I use Win 8. I recently uninstalled Firefox from C: and am looking to reinstall it on F:

I downloaded the full install package from https://www.mozilla.org/en-US/firefox/new/?utm_source=firefox-com&utm_medium=referral, but when I ran the install package, I got a pop-up window after the package extracted:

c:\users\<NAME>\appdata\local\temp\7zS171C.tmp\setup.exe The dependency service or group failed to start

Any ideas?

hello mlind1, can you see if it works by right-clicking the setup file and installing it as administrator?
