One of the user for my plugins can’t install the CCX file. It sounds like the OS is trying to open the file in Photoshop. I asked them to right-click and click “Open As” and then select the Unified Plugin Installer Agent. However, they said that is missing. I then told them to contact Adobe Support. The response from Adobe support is in this screen shot below. This CCX installer is working for everyone except 1 user, who is missing the Unified Plugin Installer Agent. Why is the Adobe support person turning them away back to me? There is nothing I can do to help them. This CCX file was created with the latest UXP Developer tool with Photoshop 23.0.0. @kerrishotts What is the tech support person talking about here? ![image](https://us1.discourse-cdn.com/flex015/uploads/xdplugins/original/2X/4/485ba71607208ab70ba3d1de7319413bca83cb5d.png) ---

I have had this with MAC when you update to OSX Monteray. The fix I have found is to Uninstall Creative Cloud Desktop App, download it again from Adobe, reinstall it and this seem to fix it ---

I don’t know why Support is redirecting back to you or what that response even means — maybe they are thinking of CEP? Anyway—first thing to try is uninstall Creative Cloud desktop and reinstall. Ian, I just updated to monterey on my local machine — I’ll see if that repros for me. ~Kerri ---

Reinstalling Creative Cloud fixed it. I was just concerned about if they were saying the plugin was old technology because it was UXP API 1 and not 2. It sounds like that isn’t the case. Thanks. ---

Maybe this is what the tech support person was seeing. The UXP console will show API 1 as being deprecated when the plugin is loaded. ![image](https://us1.discourse-cdn.com/flex015/uploads/xdplugins/original/2X/7/71f0274dac7b9d46fbdcd8f0f69d3b318117d2b5.png)
