Severity
Warning
Message
This Windows Installer database attempts to turn off Windows Internet Explorer Protected Mode (Table: Registry, Key: [REGISTRY_ENTRY]).
Background
On Windows Vista and later systems, Internet Explorer runs by default in Protected Mode. By preventing unauthorized access to sensitive areas of a user’s system, Protected Mode limits the amount of damage that a compromised Internet Explorer process or malware can cause. As a result, applications that use Internet Explorer cannot write directly to the disk while in the Internet or Intranet zones. In addition to displaying a warning message when web pages try to write to protected areas, Internet Explorer also informs the user when web pages try to run certain software programs.
Resolution
The following resolutions are available.
Manual Fix
An application compatible with the specified Windows operating system should be delivered by its manufacturer. Self-developed applications should be re-engineered to correctly handle Internet Explorer Protected Mode. When this is not feasible, the needed web sites should be added to the list of trusted sites.
Basic Auto Fix
No resolution is available.
Advanced Auto Fix
Registry entries that are responsible for turning off the Internet Explorer Protected Mode are removed in a Windows Installer transform.
This fix is enabled by default.
Note:An additional manual action is needed: the web sites should be added to the list of trusted sites.
