Failing product updates/patches will result in a greyed-out button stuck at "Installing" when you click on the patch name on the Updates tab at GFI MailEssentials > General Settings > Product Updates.
The updates tab lists all patches available and all those that have been installed or failed installation. Further details on patches that failed to install can be obtained from the debug logs for the PatchChecker plugin located at

Updates are essential and keep your MailEssentials server free from any known issues and security threats. Older versions of the product have known issues therefore the first recommendation is to ensure that you are running the latest release before proceeding with the manual update steps outlined below:
- Browse to
..\GFI\MailEssentials\Patches\directory and open the PatchDetails.xml file in a text editor.
- Locate the
<PatchRelease>tag for the patch that is failing to install (e.g. Patch 7).
- Look for the line that contains a URL and prefixed by a
<url>tag similar to: <url>http://cdnpatches.gfi.com/me/...
- Copy the actual URL into a browser (without the <url> </url> tags) to download the .cab file.
- Browse to the download location and right-click the file then select Properties.
- Unblock the file in the General tab if available.
- Unzip the cab file and the zip file contained within the cab file.
- Right-click the GFIPatchExecuter.exe and Run as Administrator.
- Note: You may need to click the Rollback button and reinstall if it previously failed to install.
