Extension Manager CC claims extension requires Photoshop 14 or greater

Extension Manager CC claims extension Requires Photoshop 14 or greater


Using Extension Manager CC to install PSDCovers generates modal error stating “This extension can not be installed, it requires Photoshop version 14.0 or greater.”

Why am I seeing this error?

Extension Manager CC was deprecated after CC 2014 — you cannot use Extension Manager CC to install Photoshop plugins for any version after CC 2014.

Deprecation Notice UPDATE

Adobe has updated the URL for the original deprecation notice which now points viewers to Creative Cloud error codes and descriptions.

Here is the original notice:

  1. View original on archive.org
  2. Download Webpage (zip)
  3. Download PDF


Adobe still mentions the deprecation on the following Creative Cloud page.



Use Adobe’s official method for installing third-party panels:

Official Install Method

  1. Go to your Creative Cloud account
  2. Click “Remove” to uninstall the PSDCovers panel.
  3. Return to our CC installation walkthrough and start again.
