Question

Probleme mit Adobe Acrobat Pro 25

User hat sich angemeldet in Acrobat und kann die Pro Tools nutzen, wenn er aber z.B. Unterschriften einfügen will, hängt sich Acrobat auf und kann nur mehr per Task Manager beendet werden. An der Firewall und am Virenscanner liegt es nicht, das haben wir getestet. Kennt das Problem wer bzw. gibt es Lösungen? Ich habe momentan die Windows UAC in Verdacht. Gibt es hier empfohlene Einstellungen?

    Ich habe auf meinem Rechner nochmal versucht in Acrobat 26.1. eine Unterschrift einzufüngen. Es kommt egals was man tut und welches JPG man verwendet. “Unbekannter Fehler” ist aufgetreten. ich habe hier nochmals aktuell Logfiles erstellt. Könnten Sie das bitte nochmal überprüfen, danke.

    Hi ​@geregl67, 

    I assume you have a work machine or are connected to a restricted network. 

    Our findings, a quick find of the logs, show: Corporate proxy or network restriction is blocking Acrobat from accessing required services
    You may visit this help document: https://helpx.adobe.com/enterprise/kb/network-endpoints.html for unblocking network ports, etc. 

    If you have a work machine, and this issue is happening with other users as well. Requesting you to ask your admin to open a ticket via Admin console, and you will be connected with the dedicated support team

     

    Let us know how it works.

    Hi ​@geregl67, 

    Sorry for the troubled experience, and thank you for reaching out. 

    Since Acrobat is crashing (and not just freezing), we would need crash logs:

    • Instructions: https://adobe.ly/44afCIz
    • Once collected, upload the logs to any cloud drive (e.g., OneDrive, Google Drive, Dropbox) and share the link with us.

     

    Also, help us with Diagnostic logs:

     Run the Adobe Diagnostic Utility

    1. Download the utility from this link: https://adobe.ly/4nqkAbE
    2. Open the tool and click Start Diagnostics.
    3. Ensure Advanced Logging is enabled.
    4. Launch Acrobat and reproduce the crash or freeze (open the “What’s New” window).
    5. Once the issue occurs, return to the utility and click Stop Monitoring.
    6. Copy the Log ID shown and share it with us here.

    Will be waiting for your response and logs.

    Thanks for the quick response, ​@geregl67!

    Based on the crash analysis, Acrobat is encountering an issue while processing image data in the PDF, specifically with JPEG content. This typically indicates that the file may contain non-standard or corrupted image data, which can cause rendering crashes.

     

    This appears to be file-specific rather than a general Acrobat issue. As a workaround, we recommend recreating the PDF using methods such as Print to PDF, Optimize PDF, or converting via Distiller, which can rebuild the file structure and resolve such issues.

     

    Additionally, you may try updating your graphics card drivers. If your system is configured for dual-card rendering, could you try disabling one for testing purposes? 

     

    If the issue persists across multiple files and environments, we can investigate further to determine whether it is a potential product defect.


    Kindly share crash logs: 

    • Instructions: https://adobe.ly/44afCIz
    • Once collected, upload the logs to any cloud drive (e.g., OneDrive, Google Drive, Dropbox) and share the link with us.

    Habe jetzt Acrobat 26.1 installiert, leider gleiches Problem.

    und dann muss man das Programm mit dem Task Manager beenden.
