Error: When opening Adobe Creative Cloud 2014 or 2015 applications: "The Extensis extension could not be loaded because it was not properly signed."

Description

When I open Adobe Photoshop, Adobe Illustrator, and Adobe InDesign CC 2014 or CC 2015, I get an error: “The Extensis extension could not be loaded because it was not properly signed.”

​

This only happens when the Extensis font panel is loaded. This issue only affects the font panel and does not affect our font auto-activation plug-ins.

Solution

Adobe Creative Cloud 2014 and 2015 displays the warning dialog because the digital certificate used to sign our panel extensions expired.

We have issued new installers with updated certificates for the following Extensis applications:
