Question details
Users are unable to load form data or execute JavaScript in FDF-based PDF AcroForms when opening them within Internet Explorer 11.
- Product
- PDF Reader / Internet Explorer 11
- Device & OS
- Windows 10
- Scenario
- Opening FDF-based PDF forms in an older web browser to enter data or submit information.
- Observed behavior
- The PDF form successfully opens in Internet Explorer 11, but the form data and embedded JavaScript fail to load or execute, even after reinstalling the browser and the PDF reader plugin.
Ensure your Windows 10 operating system is fully updated and verify that you have administrative privileges to adjust Internet Explorer's security and ActiveX settings.
Check and Adjust Internet Explorer Security Settings
Modify ActiveX and Protected Mode settings in Internet Explorer to allow legacy PDF plugins to run scripts and load form data.
Internet Explorer 11 relies on specific security configurations to run legacy plugins. Recent Windows updates or strict security policies may block ActiveX controls and Active scripting, preventing your PDF's JavaScript and FDF data from loading.
Launch Internet Explorer 11, click the gear icon in the top right corner, and select 'Internet options' from the dropdown menu.
Navigate to the 'Security' tab. Select 'Trusted sites' and uncheck the 'Enable Protected Mode' box. Click 'Sites' to add your specific form URL to the trusted list.
Click the 'Custom level...' button. Scroll down to 'ActiveX controls and plug-ins' and 'Scripting', ensuring that options to run ActiveX controls and Active scripting are set to 'Enable'.
Click 'OK' to apply the changes, close Internet Explorer completely, and reopen the browser to test your PDF form.

The most reliable method is to download the PDF form to your local drive and open it using a dedicated desktop PDF application, such as WPS Office. Desktop applications natively support JavaScript and form data without relying on fragile browser plugins.
