I noticed that after downloading the InDesign 2026 app, it removed the extensions section out of the Window panel. Has this been moved? It is critical for my company to have access to this panel. This extension isn't available on Exchange.

Hi @cindia63843767,

Thanks for sharing the update. Could you please share your operating system details? Please try completely removing both Creative Cloud and InDesign using the Creative Cloud Cleaner Tool and then reinstall them to check if that helps. You can follow the steps here: https://adobe.ly/4nzuwyF.

Once reinstalled, check if the Extensions option reappears under the Window menu after installing a compatible plugin.

Please let me know how it goes.

It was an older OpenAsset plugin and OpenAsset has now released a new
version that plays with InDesign 2026.

This should help you! It explains the best way to get the open asset plugin to work for Adobe Indesign 2026.

Cheers!

As some have mentioned, it is a compatibility issue with older Extensions that are not written using the UXP standard. Adobe dropped support for older extensions.

For us, the OpenAsset extension was a problem in InDesign 21/2026. Then OA released an updated extension (2.5.6) and it shows up in the Extensions panel now.

CEP and UXP are two different things. CEP extension is loading for me just fine with no changes done from what was working in 2025. So yeah it could be an UXP thing if the extension you are looking at is using UXP. For now, I don't see CEP support revoked for InDesign.

Could be that the extension is not compatible, maybe it's just a version number in a manifest.

I don't know whether CEP uses such numbers, and whether CEP itself had a version bump.

I tested on a MAC and the extension menu option is visible and my CEP extensions are loading fine. No version update was needed. In my hostlist defined in the manifest.xml i have kept the version like following

Hi @Chase33635940qwag,

I tested this behavior on my end and noticed that the Extensions option under the Window menu becomes visible only after installing a plugin or extension. I tried this on versions 19.5.5, 20.5, and 21.0, and they all behaved the same way.

Could you please try downloading and installing any plugin or extension and check if the Extensions option appears afterward?

Let me know how it goes.

It still does not work. I do not have Windows Extension and Adobe Createive Cloud does not recognize that I installed a Plugin

I have Extensions menu in my 20.5 version on a MAC and I have my CEP extension loading in it as well. It does happen that this menu is not displayed, I have noticed this in past versions as well. What I would suggest to do is install some extension that should load in 2026 version and it should pop up. Try it and let us know, I will try installing as well as soon as I get time

There's no Window panel so you must mean the Window menu?

Here are screenshots of the Window menu in InDesign 2025, InDesign 2024, InDesign 2023 and InDesign 2022:

Following up with @Abhishek Rao logic, here is Illustrator's Window menu in 2026.

Hi @Chase33635940qwag,

Thanks for sharing this. I checked InDesign version 20.5 on my end, and the Extensions panel isn't available under the Window menu there either. It seems this might be a mix-up with Illustrator, as InDesign hasn't included that panel in recent versions. Could you please check one of your older versions where you remember seeing it and confirm which version that was? That will help me better understand the issue.

Looking forward to your update.

Abhishek
