Install Indesign 2019

Direct Download Links https://prodesigntools.com/tag/ddl MAY help
-you MUST do what it says in Note: Very Important Instructions
-https://prodesigntools.com/adobe-cc-2015-direct-download-links.html#download-instructions
-the prodesign links go directly to Adobe's file server, so this process
--will only work until Adobe completely removes the old version(s) from the server
.
IF/When you do have a download, be sure to copy it to AT LEAST one external device
-since Adobe does sometimes remove old versions from the server
-a usb flash drive or hard drive, or write to a DVD

Hi @Sophie5EF7 ,
Only the latest two versions of the Creative Cloud apps are supported and available for download. You can try and download the CC2019 of the Creative Cloud apps from the following website. If the links mentioned on the website don't work, then it means that Adobe has discontinued providing the download and genuine installers are not available anymore. Be circumspect if someone contacts you claiming to provide an installer in such a case.
