Question

CEP Panel not showing up in Illustrator 2025

Hi,
we are developing an internal CEP extension panel for Adobe Illustrator 2025 (Windows, Czech localization). We followed all the recommended steps:

  • The panel folder is located in:
    C:\Users\<user>\AppData\Roaming\Adobe\CEP\extensions\cz.tvoje.panel.illustrator

  • The manifest file is present and references index.html and index.js

  • We have added PlayerDebugMode = 1 in the registry under:
    HKEY_CURRENT_USER\Software\Adobe\CSXS.12

  • The index.html and all paths are valid

  • We tried both the user-level and program files CEP folders

  • The panel does not appear under Window > Extensions (only "Libraries" is listed)

Is there anything new in Illustrator 2025 that prevents CEP panels from showing up?
Is CEP still supported in AI 2025 or do we need to migrate to UXP now?

Thank you very much for any advice or guidance!

    @petr_5255 -Yes, the CEP panel still works in Illustrator. Could you please share the manifest file content?"

    Best regards
