I have a rather old MacBookAir running the latest macOS 12 w/ Adobe Acrobat Reader installed:

Since a few days, trying to update (via the “Help” menu) fails with an error, so I decided to simply re-install it.  Therefore, I downloaded the installation dmg, but running it fails with

The box is running 12.x… Any idea what goes wrong here?

    I had exactly the same problem and finally found a workaround after hours of trial and error, that worked for me - maybe it does for you as well.

    1. I downloaded and installed the 10.14 base version (2022.001) from the Acrobat downloads page. This is the latest one Monterey accepts. Official Link: https://trials.adobe.com/AdobeProducts/APRO/Acrobat_HelpX/osx10/Acrobat_DC_Web_WWMUI_1014.dmg
    2. In the next step I installed the 2025.001 Update. Official Link: https://ardownload3.adobe.com/pub/adobe/acrobat/mac/AcrobatDC/2500120756/AcrobatDCUpd2500120756.dmg
    3. Next I launched Acrobat and went to Help → Check for Updates.
    4. Acrobat used its built-in updater and updated itself to 26.001.21563 (apparently the latest version it offers for macOS Monterey) instead of the newest available 26.001.21651.
    5. If you get an error (for example 1782) you can install the 26.001.21563 Update manually here: Official Link: https://ardownload3.adobe.com/pub/adobe/acrobat/mac/AcrobatDC/2600121563/AcrobatDCUpd2600121563.dmg

    Most likely it is possible to install the 26.001.21563 Update directly onto the 10.14 base version (2022.001) without updating to 2025.001 first. This could be the fastest way to become as up-to-date as possible. I didn’t check this yet. ApparentIy I took a different path searching for a solution at all.

    Anyway, the current Unified/Creative Cloud Installer refused to install on Monterey for me, but this upgrade path worked perfectly. Adobe really should document this, as it would save users a lot of frustration.

    Hope this helps.

    Update: I tried to install 26.001.21563 Update directly onto the 10.14 base version. It worked. So you don’t need step 2 to 4.

    Hi,
    thanks a lot for sharing this approach!  In my case, installing the 26.001.21563 Update package failed with an error whilst executing the package scripts.  However, the Reader claims its actually v. 26.001.21563 now, and opening documents seems to work.  Maybe the differing behaviour is related to my (German) localisation?
    Anyway, I can live with this. 👍
    Thanks again!

    Thanks for the clarification.  Please note that the download dialogue still states that the Adobe Reader rev. 21662 is suitable for macOS 12

    and that the Technical requirements web page also mentions “macOS 12 or above”:

    which is really misleading.

    Hello ​@dress.a,

     

     

    Thank you for the screenshots and for your patience while we investigated this.

     

    Version 26.001.21651 of Adobe Acrobat officially dropped support for macOS 12 Monterey as part of its system requirement changes. Since your 2017 MacBook Air is limited to macOS 12.7.6 and cannot be upgraded further, it no longer meets the minimum system requirements for this version of Acrobat. The installer error you are seeing is expected behavior, even though the wording of the error message itself is misleading.

    You can confirm this yourself by visiting the Adobe Acrobat Enterprise Release Notes at:

    https://adobe.ly/3QzJABG

    On that page, scroll down to the System requirement changes section, where you will find the entry for 26.001.21651 listing macOS 12 Monterey as a dropped platform alongside Windows 7 and Windows 8/8.1.

     

    We are sorry for the inconvenience this has caused and appreciate your understanding.
