Extensis extension not properly signed error


We’d like to make you aware of issue that affects the Extensis Font Panels included with our font managers.

The Extensis font panels provide quick access to your font collection within the Adobe Creative Cloud applications – Photoshop, InDesign and Illustrator.

Today, the security certificate used to verify the validity of our application expired. If you attempt to load Extensis Font Panel in Adobe Photoshop, InDesign or Illustrator Creative Cloud 2014 or 2015 you will receive the error “The Extensis extension could not be loaded because it was not properly signed.”

This issue only affects the panel and does not affect font auto-activation by the plug-in. We know that these panels are popular and this is why we are being proactive about notifying you.

We are aware of the issue and will be issuing updates for all of our currently supported products affected.

  • Suitcase Fusion 6
  • Suitcase Fusion 5
  • Universal Type Client 6
  • Universal Type Client 5

We expect to release patches to fix this issue within the next few days and will post the links here.

If you have additional questions please contact Extensis for more information.

I must say waiting for the certificates to expire before offering a fix is an epic fail. Do you realize this is the second time in 2 months the third in 6 that the software was completely useless to the designer? Why is quality control not emphasized more. You certainly knew the certificates were expiring. What prevented you from fixing it before it borked your customers workflow. As this is the second time in 2 months I’m unable to manage my fonts with a font manager that isn’t cheap means you are basically holding us hostage to these terribly timed mishaps. Why you have not worked closer with Adobe to smooth these transitions is beyond me. I know for a fact Adobe partners with other companies to ensure things work before they release an update. It’s enough to seriously consider an alternate font manager. This is taking money and time out of my pocket waiting for these updates to fix what shouldn’t have broke in the first place. We pay good money for this software with the expectation that it will continue to work.



We hear your concerns and are reviewing our internal processes to ensure better quality releases for future compatibility updates. We are sincerely sorry for the inconvenience this has caused you.
