When I  tried to open my CCTV Camera-DVR on Internet Explorer an activeX plug-in was required. But it failed to install and gave the following error. “windows has blocked this software because it can’t verify the publisher”

Solution that worked for me:

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.
