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.

https://github.com/Adobe-CEP/CEP-Resources/blob/master/CEP_12.x/Documentation/CEP%2012%20HTML%20Extension%20Cookbook.md

Please suggest.

Thanks

Maybe @Dirk Becker has an idea but from what I can find out

It might still use CEP 11.x. so a runtime to version 11.0 from what I can gather.

I think some parts of Photoshop and maybe some other apps have - that's probably why you're seeing docs for CEP12.

So your hotlist might need to match INDesign 2025 range, something like 20.0,20.9...

Look forward to hearing more about this and if it helps at all or I could be way off the mark. If you need more help or info let me know and I'll do more digging.
