CEP version in InDesign 2025

Hi,

What is the CEP version supported in InDesign 2025?

I have the following which does not work and gives error “Unsupported InDesign Version” with “11.0”. With “12.0” the extension doesn’t even load.

   <ExecutionEnvironment>
      <HostList>
         <Host Name="IDSN" Version="[20.0,20.9]" />
      </HostList>
      <LocaleList>
         <Locale Code="All" />
      </LocaleList>
      <RequiredRuntimeList>
         <RequiredRuntime Name="CSXS" Version="12.0" />
      </RequiredRuntimeList>
   </ExecutionEnvironment>

Even on the official CEP site I can’t find if it supports 11 or 12 for InDesign 2025.

Please suggest.
Thanks

Tried it and 12 did not load and 11 succeeded. manifest.xml looks the same.

<ExecutionEnvironment>
  <HostList>
    <Host Name="IDSN" Version="[20.0,20.9]" />
  </HostList>

  <LocaleList>
    <Locale Code="All" />
  </LocaleList>

  <RequiredRuntimeList>
    <RequiredRuntime Name="CSXS" Version="11.0" />
  </RequiredRuntimeList>
</ExecutionEnvironment>

How did you check the error message?

Apologies to everyone. The extension works perfectly with Version=“11.0”.

The error mentioned was thrown from one of our internal components loaded by the extension which I failed to recognize.

So, all good for now.

Thanks.
