I am trying to access my security cameras ofver the network. the site needs to download a *.cab file, but i keep getting: "windows has blocked this software because it can't verify the publisher"  I gave googled and used the search function on here. disabled pop-up blocker, shut off win-firewall, added to trusted sites and reset permissions, changed allow software to run or install ..., uninstalled java / reinstalled java. Still no love.  This is really starting to irk me. I trust the app, but microsoft in its eternal knowledge will not let me load it.  Any help with this would be greatly appreciated as I have exhausted my ideas.

fnbgppl--One person fixed the problem by uninstalling the WinOS then the Webcams, and then reinstalling
Disabling some of the IE Security settings might help.  But disable only while you try to download that .cab file.  Then re-enable for security reasons.

In IE Properties - Advanced -Security : There is an option which says "Allow Software to run or install even if the signature is invalid"

Enable it, by putting a check mark, then try.

Alright some more failed filaments.

Taking computer off domain, making sure time was correct, more registry changes, disabling all security, killing the firewall service, telling the computer to not look at the certificate, use firefox, downgrading ie to 6.0,  and truthfully many more. From all of this I have isolated that it is a local setting to the machine.  If anyone has any help on this I would greatly appreciate it.

Sorry edison reference.

It's not really a web cam. It is a security camera system(DVR), with a browser interface for network viewing and management.  So there is nothing currently actually installed on the computer.

 I had not tried that, but it does not try load the .cab file for the video if I go that way.
Nice trick I did not know that was there.

None of these solutions helped. It ended up being a windows upgrade issue with activex. I bypassed it by finding a comparable software and using its drivers. Thanks for the help.

I figured this out.

Don't do this unless you are absolutely sure this is a Trusted Site

Add the page (preferably an internal IP address) into your Trusted Sites.
Tools/Internet Options/Security/Trusted Sites/Sites
Add the web site. You may have to un-check
Request server verification (https:)

Then go back to the Security page, Make sure the Trusted Zone is still selected
At the bottom in the section
Security Level for this zone
Move the Bar to Low

This will allow you to install the software, but will give you warning prompts.

After the install you can Restore the Security settings back to Default Level

I take no responsibility if this screws up your machine.
I just know it worked for me
