I keep trying to download Firefox 4 using various browsers, it appears to go through the installation process successfully but never actually starts up

Question

I've tried downloading using both IE and Chrome, get all the usual processes you'd expect to install correctly, at the end I leave the box ticked for automatic startup but it doesn't start. The quickstart icon is installed on my desktop, but when I click on it it still doesn't start. When I start to delete it and re-install I always get a message saying that it's running and I have to close it down first, so it clearly thinks it's running, but there's no evidence of that. I've used earlier versions with absolutely no problem, just Firefox 4 won't perform.

Answer 1

Ok after doing some research, I came up with a solution. I'm sure the original poster has already figured something out, as it was like three months ago, but I wanted to post this anyway, for someone else that may come across this same problem. I went into my task manager (control, alt, delete) and went into processes. Look for 'firefox.exe' If you see it, end the process. Then try and run the install again. This fixed it for me, hopefully it will help somene else too.
