On July 27 something changed with Adobe Photoshop that can cause the T-Seps 3.5.5 Extension Panel to not load and to give an error that the extension is not signed. T-Seps is an authorized extension of Adobe and has been for many years and is “signed” (verified). The T-Seps extension plugin has not changed in over 1-1/2 years.
We reacted quickly and put up workarounds and temporary fixes on this page. We have now released an updated version of T-Seps 3.5.5 called Build 2.0 for both Windows and Mac.
Simply download the latest Free Trial from HERE. You should not be asked to be unlocked again and the Free Trial should overwrite the older version and update the T-Seps Extension. Make sure Photoshop is closed when you do the update. The way to tell if you have been updated is check the T-Seps Extension Panel in Photoshop. In the lower right of the T-Seps window it should say Version 3.5.5 Build 2.0.
Important notes: If you got the “Extensions signed” error and followed the link to the Adobe website – you were told to remove certain folders from your Photoshop install. Some of these folders are necessary for T-Seps to install. If you have problems with the new T-Seps NOT showing up in the Extensions window in Photoshop you might need to do a reinstall of Photoshop and a reinstall of the new T-Seps build.
We have had a few isolated cases with Mac users where the T-Seps 3.5.5 Separation Suite does not show up in the Extensions panel after installing the upgrade. We are trying to duplicate this issue (without success) but there are things to check and the ability to revert back to T-Seps 3.5.5 build 1.50 and use a temporary fix. Click HERE for details.
