Solution 1Recommended

Disable Protected Mode and Enhanced Security for Testing

Temporarily disable Acrobat's built-in security modes to determine if they are conflicting with your system or document and causing the application to crash.

Adobe Acrobat includes Enhanced Security and Protected Mode features designed to protect your computer from malicious code. However, these strict security environments can sometimes cause conflicts with certain plugins, system configurations, or complex document elements, leading to freezes when executing standard commands like Print or Save As.

1
Access Acrobat Preferences

Launch Adobe Acrobat. Click on 'Edit' in the top menu bar and select 'Preferences' from the dropdown list.

2
Navigate to Enhanced Security Settings

In the left-hand pane of the Preferences window, scroll down the categories and click on 'Security (Enhanced)'.

3
Disable Protected Settings

Uncheck the box that says 'Enable Protected Mode at startup'. Then, change 'Protected View' to 'Off', and uncheck the 'Enable Enhanced Security' box. Click 'OK' to apply the changes.

4
Restart and Test

Close Adobe Acrobat completely and reopen the application. Open your PDF document and attempt to use the 'Print' or 'Save As' command to see if the issue is resolved.

Disable Protected Mode and Enhanced Security for Testing
Restore Security Settings After Testing: These changes are primarily for testing. If this resolves the freezing issue, it indicates a document, plug-in, or system conflict. It is highly recommended to investigate the specific conflict and re-enable these security features to keep your computer protected.

Frequently Asked Questions

Why does Acrobat say an unimplemented or obsolete function was called?

This error typically occurs due to corrupt installation files, conflicts with third-party plug-ins, or incompatible system security settings that restrict Acrobat from executing specific background commands required for printing or saving.

Will reinstalling Acrobat fix the freezing issue?

Reinstalling can sometimes replace corrupted program files. However, if the issue is caused by strict preference settings like 'Protected Mode' or an incompatibility with your OS, reinstalling alone may not resolve it until those settings are manually adjusted.

Is it safe to leave Protected Mode disabled in Acrobat?

It is generally not recommended to leave Protected Mode or Enhanced Security permanently disabled, as they act as a sandbox to protect your system from potentially malicious PDF files. Only disable them temporarily for troubleshooting purposes.

Can a specific PDF file cause Acrobat to stop responding?

Yes, a complex or corrupted PDF file, especially one with heavy embedded fonts, high-resolution graphics, or intricate interactive forms, can cause the software to freeze when attempting to process the document data for printing or saving.
