Récupérer inDesign CC 2020 (15.1.3)

Adobe never released public download links for CC2020, since it's already an unsupported version(only the latest two versions are supported) there is a very slim chance that you would get a genuine installer. The last effort you could try is contacting Adobe and asking for it, you might get lucky.

To contact support, login to your account and navigate to the URL below. Make sure that the browser has cookies enabled, and all script blockers are disabled.

Type AGENT to avoid bots and talk to a human.
 On another note if you can work with versions like 2019 or older then you can checkout the ProdesignTools website @BobLevine mentioned and you might get a link to the installer(these installers are provided from Adobe servers so totally safe and genuine to use).

17.0.1 is InDesign 2022. Adobe only support and maintain installation for the current and most recent version which is InDesign 2021 version 16.

I'm sorry to tell you that there is no way to get InDesign 2020 through Adobe. However, the links, if they are still available, would be safe to download from here: How to Get the Adobe Creative Cloud 2020 Direct Download Links | ProDesignTools

Bonjour,

Cette page semble indiquer la marche à suivre (https://helpx.adobe.com/download-install/using/install-previous-version.html). N'oubliez pas, ensuite, de désactiver le "auto-update".

Cordialement,

Olivier
