You have installed Adobe using the GenP method, which functions identically to the Adobe software itself. As such, you can only rollback to versions within the current major version (CC2025) or the previous major version (CC2024).
Adobe removed direct access to all older downloads some time ago. The only way to obtain these older versions now is either through your own genuine CC account or by contacting Adobe Customer Support to request them.
If this doesn't meet your needs and you still want older versions, you'll need to follow Guide#4 Full Clean to completely remove the existing Adobe install done through the GenP method. Afterward, you can use the Monkrus method for both newer releases and any older versions, including CC2023 or earlier.
Just be sure never to mix GenP and Monkrus, and never run GenP on a Monkrus installation.
If you need further assistance, feel free to post in the appropriate channel on Revolt.
Note: This channel is specifically for GenP-related questions and issues. Your query, however, concerns obtaining versions from alternative third-party or outside sources, which is not related to GenP.
Apart from GenP, Monkrus is the only alternative we recommend. Most other methods typically involve using leeched versions of Monkrus.
Monkrus is safe to use, as it is simply prepatched with GenP files and methods, except for Acrobat, which is only patched after it is fully installed.
For more details, refer to the Monkrus Setup, Troubleshooting, and Best Practices Guide.
