    cannot run flash installer or firefox setup

    I am running Windows 8 on an HP laptop.
    I have downloaded flash 11 and Firefox 18. When I try to run either the flash installer or the FF setup file from the download folder on my computer, nothing happens The files will not open.
    I disabled my virus software in case that was causing a conflict but that didn't help
    Can anyone help? thanks

    Hello Barcann,

    You might see if using the standalone installer for Adobe Flash Player (Plugin-based browsers) version may work better for you with Firefox.

    Hope this helps,

    thanks for your advice.
    I just tried that but I cannot seem to open the installer file.
    something keeps blocking all these files

    What AV program do you have installed?

    You might add the Adobe .exe or .msi file to it's exception list (if an available option) to see if that may help.

    I have Norton installed. I do not know how to add anything to an exception list.
    I tried right clicking the files and run as an administrator.. when I do that, the pop up window asking if I want to allow this program to make changes ... appears. I click yes..nothing happens...
    it goes no further
    I am running Norton. I have that disabled.
    something will not allow me to install either FF update or flash Player (any version).
    also when I try installing Flash player as a plug in through the browser ( FF 16) it downloads and starts the install, and then just hangs... never completes the install

    As a test to see if Norton may be responsible, temporarily uninstall Norton completely and see if you still have the same issue afterwards.

    If needed, Symantec has a Norton Removal Tool if it will not uninstall normally.

    thanks so much for your help. I removed..I think..Norton.. the Norton removal tool actually hung up at removing folder trees and I had to reboot.
    but I was able to run some install programs including Flash 11 and Ad-Aware, which is now protecting my computer.
    so I think it was Norton all the time.

    Great news.

    If you like, the included Windows Defender in Windows 8 is a good AV program to use.
