Blocked software because publisher is unknown

Discussion in 'Windows Vista Security' started by Frank McGlynn, Jul 15, 2007.

  1. I am trying to access a real estate virtual tour from a reputable web site.
    When i try to run the tour an active x bar shows at the top of the page.
    When I select install, i get a message saying "windows has blocked this
    software because the publisher is unknown" The only button is "ok:. How do I
    disable whatever is causing this blockage? Thanks.

    I'll just forewarn you. You got to be real careful as to an ActiveX control
    being installed on Vista like that. It can take Vista down if it's not Vista
    compatible. I only had to visit a Web site one time that I let a ActiveX
    control be installed.

    Explore started going into a crash and restart loop that I couldn't get out
    of it The only way out was boot of the Vista install DVD to do a restore to
    get back to a point that the ActiveX control was not there.

    I am just telling to be careful, and if nothing else, communicate with the
    site's Web Admin or someone before you proceed.

    I would recommend adding the site to your trusted sites list (Tools ->
    Internet Options -> Security tab -> Click on Trusted Sites -> Click
    Sites button)

    You may need to uncheck the checkbox if the site is not a secure site.

    Then, change the security settings for trusted sites to allow unsigned
    activex controls to prompt (click custom level..., change download
    unsigned activex controls to prompt)

    controlling this. I say this because it says windows blocked, not ie7. Thanks

    This happened when I was at a friend a few days ago. Using IE we
    couldn't get Facebook to install its ActiveX control even though first
    time round we said to install it. After a refresh of the page, Windows
    decided to block the control and the IE options were set to 'Prompt' but
    Windows over-ruled that decision.

    Facebook works for me at home without having done anything 'special' so
    it isn't Vista afaik because my friend has XP on his laptop.

    We ended up using Firefox to view the pages!
