Windows has blocked this software because it can’t verify the publisher

Error “Windows has blocked this software because it cannot verify the publisher” when you try to access a website which tries to install addons or run executables like installation CAB files.
By default Internet Explorer disable running unsigned ActiveX controls. Unsigned activeX controls are programs that tries to execute a command on your PC, like CAB install files or a ZIP file which do not have a digital signature.
While this is an important security measure on the Internet Explorer browser, if you are sure that the website is a trusted one then you can temporarily disable this security feature to get the website run the required ActiveX and later on re-enable the security.
To disable this feature,
1. Open internet explorer, click Tools – Internet Options.
2. Click the Security tab – Custom Level button.
Under ActiveX ensure the following are set to enabled
Run ActiveX and plug-ins – Enabled
Download Signed ActiveX Control – Enabled
Script ActiveX controls marked as safe for scripting – Enabled
Set the following to “Prompt”
Download unsigned ActiveX Control – Prompt
Initialize and script ActiveX controls not mark as safe – Prompt
3. Click OK and Apply and OK. Restart the browser.
You should now be able to run the ActiveX control on the website. As I said earlier, please ensure that you have the above to what it was before.

so many times i stand behind ms when others gripe but stuff like this is ridiculous. I really get closer and closer to linux on a regular.
doesn’t work, I still get the “Windows has blocked this software because it cannot verify the publisher” message
clearly it’s not possible to get past these ridiculous fascist “security” settings
if only windows was this good at solving REAL security issues as opposed to blocking us from doing day to day tasks
Worked great for me – thanks!
And yes, windows should not protect us from ourselves, but concentrate on protecting their software from others….
Does’nt work for me either. Windows is blocking the active-x installation.
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
Even putting site into Trusted Zones and reducing security level to low still doesn’t work. But the strange thing is Google Chrome has no problems at all. Instant load of page and data requested.
Although warning talks about Windows security it must be something in IE that is cauing the block because Chrome works.

In IE7, add the site to the trusted list, then click Custom, and change “Download unsigned ActiveX controls” from Disabled to Enabled or Prompt.
Hi
I have tried all possible things like go to ->Tools->Security options and select proper Webzone for all 4 options. It didn’t worked. I have also go to Site tab and defined my trusted site but all gone in vain.
I have checked option in Tool -> Advanced tab -> Security option but all time a popup prompt install Digital certficate. After intall it gives error of Runtime js exception that it could not support Digital Certificate features.
Now, what could i do next ???
Great info – Works for me
Try removing the check box for “protected mode”, this worked for me for an unsigned setup i needed. Despite being in a trusted zone and low settings.
You have to restart IE every time you dork with these settings btw, otherwise you are just wasting your time.
After messing with these options for quite awhile I could not view my security cams. I was attempting to view DVR cameras thru a VPN using IP and its integrated web server. My issue was I needed to install activex and download a file from a unsigned provider.
My solution
I put all my levels to low and unchecked the protected mode.
After restarting IE I was able to view the cameras.
Solution 2 Download IE TAB for firefox, add the IP as a site you wish to always use a IE tab for and bingo no issues no BS and it will always switch the rendering engine automatically.
Never use IE and if you have to never surf the web with setting on low. You will catch a virus fast.
Hope this may help someone
