I recently have been unable to use IE9 to load a website critical to my job. When I browse to the website, I get the following warning box:
Internet Explorer blocked this website from installing and ActiveX control.
There is an install button on that warning box, which I click and then get a security warning pop-up:
The publisher could not be verified. Are you sure you want to install this software?
I click install and the website fails to load without further messages.
Troubleshooting steps I've tried so far (listed in chronological order):
- Checked for updates on Windows Update (none)
- Reinstalled Adobe Flash
- Enabled compatibility view
- Cleared everything under "browsing history"
- Added to Trusted Sites list
- Disabled internet security software
- Disabled all add-ons
- Reset all internet settings
How do I figure out why IE is blocking this site?
