habe gestern neu installiert . Habe beim Start von Word oder Excel die Fehlermeldung:

Laufzeitfehler 53
Die Datei wurde nicht gefunden: /Library/Application Support/Adobe/MACPDFM/MACPDFM.framework/Version/A/MacPDFM.

Eine Neuinstallation hat nichts geändert.

    I reinstalled yesterday office 2021 for Mac Home. I got the error message when starting Word or Excel:

    Runtime error 53

    The file was not found: /Library/Application Support/Adobe/MACPDFM/MACPDFM.framework/Version/A/MacPDFM.

    A new installation has not changed anything.

    Is a Mac Studio with M1

    How can I solve this?

    Here are the steps to eliminate that error message:

    1. In the Finder, hold down the Option key while clicking on the Go menu and choosing Library. Your hidden user Library folder opens.
    2. Navigate to ~/Library/Group Containers/UBF8T346G9.Office/User Content/Startup.
    3. Open the Excel folder and drag SaveAsAdobePDF.xlam to the trash.
    4. Open the Word folder and drag linkCreation.dotm to the trash.
    5. While you're there, open the PowerPoint folder and drag SaveAsAdobePDF.ppam to the trash.
    6. Open Word or Excel and test that the error no longer appears.
