Installing a UXP panel (from a CCX file)

This page offers instructions on how to install a UXP panel locally from a downloaded CCX file (this apples to the new UXP version of Lumenzia). If you do not have Photoshop v23 or later, you will need to run the CEP version of Lumenzia (see here to install the older CEP version of Lumenzia). If you are trying to install Web Sharp Pro - that is also a UXP panel, but is distributed through the Adobe marketplace rather than as a standalone CCX file (see here to install through the Adobe Marketplace).

If you are installing a UXP panel purchased through the Adobe Marketplace (such as Web Sharp Pro), you will not have a CCX file and should instead follow the instructions for installing a UXP panel from the Adobe Marketplace.

Installing from a CCX file:

  • The Lumenzia ZIP file contains both the older CEP/Flash versions of Lumenzia and the newer UXP version. Just locate the file with the CCX file and double-click it.
  • DO NOT use "open with" or try to open the CCX file with either Photoshop or the Adobe installer. This will fail. The correct app is a hidden Adobe helper app that you wouldn't know about (it then loads the CCX in the Adobe installer, but that installer will not accept the file directly). If you have changed the default app, please see the steps below to change it back to the correct app.
  • This should open the Adobe Creative Cloud Desktop (CCD) installer and ask you to confirm you wish to install.
  • Go to the Plugins menu in PS if you do not automatically see the panel open in Photoshop (it won't show if Photoshop was closed during installation).

That's one of the main benefits of UXP, these panels are quite easy to install generally.

Note that if you have the CEP version of Lumenzia installed, it may be ideal (but is certainly not required) that you uninstall it or close it so that you free maximum resources for Photoshop. Simply closing it and restarting Photoshop gives you all the benefit, uninstalling it will save a tiny bit of extra space on your drive.

If you run into problems, please see the troubleshooting section below.


CCD says you do not have a compatible app installed:

The CCX file won't open or you get a warning "Creative Cloud cannot open files of this type." or "Could not complete your request because Photoshop does not recognize this type of file":

  • This may indicate that you do not have the Creative Cloud Desktop app installed. If you have Photoshop CC, then you should have this.
  • This more likely may indicate that the CCX file extension is not pointing to the correct Adobe app. While the app you see is Creative Cloud Desktop, installing a local CCX file actually occurs through a helper app. Make sure that your operating system is pointing to the correct app:

    MacOs: /Library/Application Support/Adobe/Adobe Desktop Common/RemoteComponents/UPI/UnifiedPluginInstallerAgent

    Windows: C:\Program Files\Common Files\Adobe\Adobe Desktop Common\RemoteComponents\UPI\UnifiedPluginInstallerAgent
  • If you're still having trouble, please contact [email protected] to help understand why your system will not install a valid CCX

I installed the panel, but cannot see it in Photoshop:

  • Go to the "Plugins" menu in Photoshop to launch any installed UXP panels (older CEP panels are under a different menu area: Window / Extensions)

  • Check that you have reasonable free space on the drive.
  • If not free space, the issue is likely permissions. Reinstalling the Adobe Creative Cloud installer is likely the solution.

Adobe Creative Cloud : Error -10:

  • Make sure you have the CCX file on the boot drive and then double-click there.
