DTBI350-IE11 - Software must be disallowed to run or install with invalid signatures.

Information

Microsoft ActiveX controls and file downloads often have digital signatures attached that certify the file's integrity and the identity of the signer (creator) of the software. Such signatures help ensure unmodified software is downloaded and the user can positively identify the signer to determine whether you trust them enough to run their software.

Solution

Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Advanced Page -> 'Allow software to run or install even if the signature is invalid' to 'Disabled'.
