I cannot download a new version of Mozilla (but also not from Explorer or Google Chrome). I downloaded the software several times already, but still I cannot update any program. Can you help me out please?

Question

I am using an older version of Mozilla (i cannot see which version), but somehow this version is so old that I cannot use Hotmail or Internetbanking properly anymore. Therefor I wanted to update my Mozilla-program, but unfortunately this isn't possible. I downloaded your new version Firefox Setup 7.0.1.exe and I see this in the file 'downloads'.
If I want to click it, it says '“Firefox Setup 7.0.1(4).exe” is een uitvoerbaar bestand. Uitvoerbare bestanden kunnen virussen of andere code bevatten die uw computer kan beschadigen. Wees voorzichtig met het openen van dit bestand. Weet u zeker dat u “Firefox Setup 7.0.1(4).exe” wilt starten?'
Then I click 'Oke'....to tell the system I want to start the program. Then I get another pop-up: 'securitywarning......'
Then I click on ' continue' and I have to choose a program to open this program. I can choose from iexplore.exe or firefox.exe.
If I choose for firefox.exe.....nothing happens.
Quit strange. I am quit well with computers, but this is really strange to me.
Hopefully you can help me?

Answer 1

I finally figured out what was wrong.  Since I had installed Google Chrome recently it already had the Adobe Flash Player imbedded in it. 
When I uninstalled the flash player in Control Panel option the problem went away.
