Issue Summary – PDF Opening Issue Windows 10

After installing KB5003637 or later updates in the affected Windows version, you might experience problems that prevent you from opening PDFs using Internet Explorer 11 or apps that use the 64-bit version of the web browser control. Additionally, a PDF might render as just a grey background when using the Adobe Acrobat plug-in.

Note – Internet Explorer is only affected if Enable 64-bit Processes for Enhanced Protected Mode is enabled in the Advanced tab in Internet Options.

Workaround

To mitigate the issue, you can use one of the following:

  • Open the PDF file directly in Adobe Acrobat instead of within IE11 or the affected app.
  • For IE11 only: Disable the setting Enable 64-bit Processes for Enhanced Protected Mode in the Advanced tab of Internet Options.
