Installing, Updating, and Removing UXP extension panels

Installation of UXP panels is done through the Adobe Creative Cloud Desktop (CCD) app. You can install on all the computers you install Photoshop on when purchasing via Adobe Creative Cloud.

To install a panel you have purchased through the Adobe Marketplace:

Open Photoshop and go to Plugins / Manage in the top menu. This will invoke CCD and take you to the page listing all the plugins you've purchased.
Look for the plugin and click "Install". [Note: if you do not see the plugin you expect, you have either not purchased it, or you purchased it with an email which does not match your Photoshop login. If you need to change the email used for purchase, please contact [email protected].]
If Photoshop was open at the moment you installed, the panel will be opened and floating (probably towards the top-left of the screen). Just click and drag the title tab of the panel to place it wherever you like.
If Photoshop was not open during installation, then the panel will not be shown automatically when you start Photoshop. To open it, go to the Plugins menu in Photoshop and and you should see it there. This is where you should go to reopen a plugin anytime you may have closed it.

If you need to purchase the panel :

Click Plugins / Manage Plugins in Photoshop to open CCD. Then click "All plugins" in the left column, and then use the search field immediately underneath all plugins (there is another search field at the top right - do not use that other search field, it will not search UXP plugins).
Click the "Buy" or "Get" button and then confirm by clicking "OK".
If you already purchased and still see a "Buy" button, be sure that you are logged into the same email address used for purchase. If you still need help, please contact [email protected].

Troubleshooting install problems for plugins in the Adobe Marketplace:

If your issue is not addressed directly below:

See my list of known Adobe bugs and workarounds.
For information on other errors, review this page for installing from a local CCX file (while that is meant for Lumenzia, a decent number of the concerns apply to either method of installation).
Please see Adobe's troubleshooting guide or contact [email protected].

Issue: Adobe Installer (CCD) warns "compatible app required":

Please check that CCD actually shows Photoshop as installed. There is a bug where PS may be installed, but the Adobe installer does not recognize it. The solution is to uninstall and reinstall Photoshop (you may keep your preferences during the process).
Make sure you have a normal version of PS installed and not just the PS beta. The installer will work for the beta, but for some reason does not seem to consider it when doing checks for valid applications.
Make sure you are running a supported version of PS (currently Web Sharp Pro v6.4 requires PS v24.4 or later).
Please see Adobe's support site for more info: https://helpx.adobe.com/creative-cloud/kb/troubleshoot-common-addon-installation-issues.html

Issue: Adobe installer (CCD) shows the app as installed, but it does not show in the Photoshop "Plugins" menu:

See the troubleshooting for this topic on this page (same considerations whether installing from Adobe or a local CCX file).

Issue: I've already bought the panel and CCD still shows "Buy" instead of "Install"

This will happen if you purchase using an email address which does not match the one you normally use to log into Photoshop/CCD.

Please contact [email protected] for assistance. They will likely advise you to make a second purchase under the matching email and request a refund on the first purchase.

Issue: I do not see the latest version in the Adobe Creative Cloud Desktop (CCD) installer

Fully quit CCD (don't just close the window, you should be prompted to confirm quitting) and restart it. Or restart the computer. If the update is new in the past 24 hours, you may need to wait and then do the restart later to allow time for it to propagate.

Issue: Status Code Error 401 or 1001

This indicates that CCD cannot connect properly to the internet. Make sure you do not have ad blocking or other similar programs preventing CCD from working properly.

There are two possible ways to update plugins.

If you installed the plugin directly from CCD (no CCX file), then the plugin should update itself automatically (this is the process for Web Sharp Pro). You may use the "check for updates" option in CCD or restart your computer if you do not see it. Note that uninstalling should be avoided, as this will delete any panel-specific data (such as preferences for the panel).

If you installed locally via a CCX file, then you can update the same way you installed the first time. You just double-click the CCX file and proceed. Again, do not uninstall or you may lose panel-specific data.

You may simply close a panel by right-clicking it, which may be better than uninstalling if you ever need to use it again. Or just disable it in CCD (same place you choose to uninstall).

To uninstall: click Plugins / Manage Plugins in Photoshop to open CCD.
Locate the panel and click the ... icon and then uninstall.

Caution: Uninstalling will delete all panel-specific data (such as preferences for that panel) without warning. If you are using Web Sharp Pro, click Tutorials and see the instructions for backing up if you wish to preserve your data when uninstalling.
