CEP panel for After Effects 2025

Hi everyone,

I'm trying to develop a CEP panel for After Effects 2025, but it's not showing up in the application. Here's what I've done so far:

I created the folder structure with manifest.xml, index.html, and main.js.

The manifest.xml is configured with:

xml
copy
Edit
<ExtensionBundleId>com.victor.elevenaudio</ExtensionBundleId>
<Extension Id="com.victor.elevenaudio.panel" Version="1.0"/>
<Host Name="AEFT" Version="[16.0,99.0]"/>
<RequiredRuntime Name="CSXS" Version="12.0"/>
I placed the folder at:
C:\Program Files (x86)\Common Files\Adobe\CEP\extensions\com.victor.elevenaudio.panel

I enabled debug mode in the Windows registry:


[HKEY_CURRENT_USER\Software\Adobe\CSXS.12]
"PlayerDebugMode"=dword:00000001
I restarted After Effects and still don’t see the panel under Window > Extensions (Legacy).

I’ve also checked folder permissions and tried rebooting the machine, but nothing seems to work.

Is there anything else that needs to be done in AE 2025 to make unsigned CEP panels appear?

Thanks in advance!
