When you try to create a PDF using Adobe PDF Printer or the Convert to Adobe PDF (PDFMaker function) feature from various applications, you see the following error:
To fix this problem, try the following solutions in the order they appear below.
Solution 1: End the acrotray.exe process using the Task Manager
- Press Ctrl+Alt+Delete on your keyboard, and then click Task Manager.
- On the Processes tab, click the AcroTray.exe process to highlight it.
- Click End Task. You may see a warning message, click Yes to confirm.
Solution 2: Confirm that the PDF creation is working fine from within Acrobat
- Sign in with an account that has a valid subscription, if prompted.

Solution 3: Temporarily disable programs that perform virus scans, and repair Acrobat
Programs that scan virus can conflict with the activation process of Acrobat. Before you activate Acrobat, temporarily disable such programs:
- Virus protection software (for example, McAfee, Norton Anti-Virus)
- Firewall software (for example, ZoneAlarm, Norton Internet Security Suite)
- Software that stores deleted files or remove temporary files from the system (for example, Norton SystemWorks)
For instructions on how to disable or enable a program, see its documentation. To disable firewall software, contact your system administrator.
Note:
Disabling the software firewall can leave your computer vulnerable. Disabling the software does not ensure that all functions of the software are disabled.

Like most Windows applications, Acrobat and Reader use Microsoft Windows Installer technology for installing updates. If the update fails, you can get one of the following Microsoft Installer errors. The list is not comprehensive. Adobe updates the list as it learns more solutions to common errors. If your error is not listed here, you can check Windows Installer Error Messages on the Microsoft site.
