Fix a Certificate Error in Internet Explorer
A certificate error message in Internet Explorer is designed to pop up when the browser detects a website's security certificate contains invalid information. This is done to protect Web surfers from malicious websites that can download viruses or fake websites set up to gather personal information. But sometimes this security feature goes awry and begins to block trusted sites the user knows are safe.
Instructions
1. Close Internet Explorer, then click the Start button. Type regedit in the search box if you are running Vista or in the run box if you are running older versions of Windows. Hit Enter.
2. Highlight HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl by clicking on it.
3. Highlight New in the edit menu and click Key.
4. Type FEATURE_ERROR_PAGE_BYPASS_ZONE_CHECK_FOR_HTTPS_KB954312 in the new key box and hit Enter.
5. Highlight New in the edit menu and choose DWORD Value.
6. Type iexplore.exe in the value box and hit Enter.
7. Choose Modify in the edit menu and enter 1 in the modification area. Click OK.
8. Close the registry editor and open Internet Explorer to see if the certificate error problem is fixed.
Tips Warnings
Before you attempt to fix the problem through a registry repair, check to make sure the date and time on your computer is correct. Often, something as simple as adjusting your clock settings can fix an invalid certificate error.
Also check your security settings. Sometimes security software will block a webpage for no apparent reason. If you trust the website, adjust your software to allow IE to display the page.
