Question details
The user needs to understand why Adobe Acrobat Pro 2017 or Reader DC displays a restricted Save As window and how to allow overwriting of temporary PDF files.

- Product
- Adobe Acrobat Pro 2017 / Acrobat Reader DC
- Device & OS
- not provided
- Scenario
- Attempting to use the Save As function to overwrite temporary PDF files generated by document-management systems.
- Observed behavior
- The Save As workflow behaves differently than expected or completely blocks the user from saving and overwriting files due to background security restrictions.
Before modifying your Adobe Acrobat security settings, verify that your document-management system is fully compatible with your current PDF software version.
Disable Protected Mode in Adobe Reader
Disabling Protected Mode removes the sandbox security restrictions that block the Save As function, allowing you to overwrite temporary files.
Adobe's Protected Mode acts as a sandbox to prevent malicious files from making changes to your system. While it enhances security, it can inadvertently restrict necessary file operations like Save As when interacting with temporary files from external document-management systems.
Launch Adobe Acrobat Reader DC. Click on Edit in the top menu bar and select Preferences from the dropdown menu.
In the left-hand Categories pane of the Preferences window, scroll down and click on Security (Enhanced).
Under the Sandbox Protections section, uncheck the box labeled Enable Protected Mode at startup.
Click Yes on the confirmation prompt, then click OK to save your changes. Restart Adobe Reader for the new settings to take effect.

Verify Acrobat Pro Capabilities and Default Settings
Ensure that your system is using Acrobat Pro rather than Reader, as Acrobat Pro generally bypasses these specific sandbox limitations.
Save and Edit PDFs Effortlessly with WPS Office
If strict security settings in other software are disrupting your workflow, WPS Office offers a powerful, built-in PDF editor that handles file saving, editing, and management without unnecessary Save As restrictions.
- 1. Open the PDF: Launch WPS Office and open your temporary PDF file directly using the built-in PDF reader.
- 2. Edit the Document: Make any necessary edits, signatures, or annotations using the intuitive top toolbar.
- 3. Initiate Save As: Click on the Menu icon in the top-left corner and select Save As to choose your preferred destination folder.
- 4. Confirm Save: Name your file and click Save to seamlessly overwrite the existing document or create a new one.

Frequently Asked Questions
Why does Adobe Reader block the Save As feature?
Adobe Reader often blocks the Save As feature when Protected Mode is enabled. This is a built-in sandbox security measure designed to prevent potentially malicious PDF files from writing or modifying data on your local system or network.
Are the Save As windows different in Acrobat Pro 2017 and Reader DC?
Yes, Acrobat Pro 2017 and Reader DC may present different file-saving workflows. Reader DC frequently enforces stricter protected views, while Acrobat Pro generally grants full local file-saving capabilities without the same sandbox limitations.
How do I know if my document-management system is causing the save error?
You can determine this by downloading a PDF directly to your desktop and attempting to Save As. If the file saves normally from your desktop but fails when opened directly from the document-management system, the system's temporary file permissions or Adobe's Protected Mode are likely causing the conflict.
