Hi, user report that they can’t install my CEP extension. The extension has InDesign 18 as minimum. The error message says that v21.5 is required. Is this a bug or why is this happening? Can this be resolved somehow? Any help appreciated! Thanks! [CleanShot 2026-04-14 at 22.27.09@2x]

After going back and forth with engineering a bit… do you see this error in the Creative Cloud desktop app if InDesign 21.3 is not installed first? I’m also told to please run the Log Collector and share the logs (not in this forum): https://helpx.adobe.com/creative-cloud/apps/troubleshoot/diagnost…

It is most likely this same Adobe error where they cannot correctly identify the app is available if the language is not english [image] No compatible apps Photoshop Well that feels really dumb. I’m changed my language preference in CC app, then had to re-down…
