I need to downgrade Adobe InDesign to 18.0 version

Hi @Daniele22113635fheb,

Thank you for reaching out.

Based on your query, it seems you're looking to download Adobe InDesign version 18.0 from the Creative Cloud Desktop app but are unable to find it listed under the "Other Versions" section. Please confirm if this is the request you'd like assistance with.

When using the Creative Cloud Desktop app, Adobe typically allows access to the current version of an application along with the previous major release. Versions older than that are generally not available for direct installation through the desktop app.

As checked, you have an active Teams subscription associated with the Adobe ID used to post this query. I recommend considering the following options:

Create Named User Licensing Packages: You can create a Named User Licensing Package from the admin console.

 Create a Package – Choose Managed Package and click Next.
Configure Package – Select OS and processor type. Enable Use OS Locales if needed. Click Next.
Choose Apps – Select the required applications. You can also create a lightweight package without apps. Click Next.
Filter Applications (Optional) – Options include:
Latest versions
Long-term supported versions
Beta apps
Older versions
Choose Plugins (Optional) – Add compatible plug-ins if required. Click Next.
Configure Options – Adjust package settings as needed and proceed.
For more details, refer to the full guide: Create Named User Licensing Packages.

Download Older Versions Directly: You can also check Adobe's archive of older versions by visiting this link.  Follow the instructions provided to download and install the desired version.
