Users may see an Adobe Acrobat/Reader error when opening PDFs in their browser, showing: “There is a problem with Adobe Acrobat/Reader. If it is running, please exit and try again. (0:521)”.
This article describes the issue and points to resources that will help you resolve it.
1. Issue
Users may encounter the error: “There is a problem with Adobe Acrobat/Reader. If it is running, please exit and try again. (0:521)”. It often appears when opening PDFs in-browser (e.g., Internet Explorer) and typically resolves on a second attempt.
This issue is related to Adobe settings, not with application, and can be resolved by adjusting Reader configurations or updating the software.
2. Solution
This issue is not with Ideagen Quality Management Core but with Adobe, with the likely causes being:
- Adobe Reader plugin misconfiguration.
- Protected Mode or Enhanced Security interfering with rendering.
- Outdated Adobe Reader version or lingering processes.
Ask your IT Team to follow the steps on the Adobe Product Community to resolve this issue.
