CEP Extension not showing up in Adobe Media Encoder (v25.5 / v24)

Hi everyone,

I’ve built a lightweight CEP extension for Adobe Media Encoder (v25.5) and placed it in the usual extension locations:

• C:\Program Files (x86)\Common Files\Adobe\CEP\extensions\com.xcast.ame.bridge
• C:\Program Files\Common Files\Adobe\CEP\extensions\com.xcast.ame.bridge
• %APPDATA%\Adobe\CEP\extensions

I also verified that the required registry keys are set:

• HKCU\Software\Adobe\CSXS.13 PlayerDebugMode = 1
• HKCU\Software\Adobe\CSXS.12 PlayerDebugMode = 1

Despite this, the extension never appears in Window > Extensions inside Media Encoder.

I even tried rolling back to AME v24, but the panel/extension menu is still missing.

Has anyone successfully enabled CEP panels in recent versions of AME, or is there an additional step/setting I’m missing?

Thanks in advance!
