Fix Cannot Download PDF Email Attachments in Internet Explorer
Question details
The user is unable to download or view PDF email attachments using Internet Explorer after recently updating their Adobe Reader software.

- Product
- Internet Explorer / PDF Reader
- Device & OS
- not provided
- Scenario
- Attempting to download or open a PDF email attachment directly from a webmail client in Internet Explorer.
- Observed behavior
- The PDF attachment fails to download or display correctly in the browser, likely due to a plugin conflict caused by the software update.
Verify if the issue is specific to PDF files or if all email attachments are failing to download. As a quick workaround, try right-clicking the attachment link and selecting 'Save target as...' to bypass the browser's PDF viewing plugin.
Configure PDF Add-on Settings in Internet Explorer
Ensure that the PDF reader add-on is enabled and properly configured in Internet Explorer to allow in-browser viewing or downloading.
Software updates can sometimes reset browser preferences or disable active plugins. Re-enabling the extension usually restores the browser's ability to process PDF attachments.
Launch Internet Explorer, click the Tools icon (gear) in the upper-right corner, and select 'Manage add-ons' from the drop-down menu.
Under 'Add-on Types' on the left side, select 'Toolbars and Extensions'. Then, click the 'Show' dropdown menu at the bottom left and choose 'All add-ons'.
Locate your PDF Reader add-on (such as Adobe PDF Reader) in the list. Click on it, select 'Enable' in the bottom right corner, and then restart Internet Explorer to test the email attachment.

Force File Download Instead of In-Browser Viewing
Disabling the browser plugin forces Internet Explorer to download the PDF as a file rather than trying to display it, bypassing display errors.
Repair Your PDF Reader Installation
A recent update might have corrupted the installation files, preventing Internet Explorer from interacting with the PDF reader.
Easily Open and Manage PDF Attachments with WPS Office
Bypass legacy browser plugin issues by using WPS PDF. WPS Office offers a lightweight, built-in PDF reader that allows you to easily view, edit, and manage all your downloaded email attachments without relying on buggy browser extensions.
- 1. Download WPS Office: Visit the official website to download and install the free WPS Office suite on your computer.
- 2. Download Your Attachment: Save the PDF email attachment directly to your computer's Downloads folder from your browser.
- 3. Set as Default PDF Viewer: Right-click the downloaded PDF, select 'Open with', choose 'WPS PDF', and check 'Always use this app to open .pdf files'.

Frequently Asked Questions
Why did updating my PDF reader break downloads in Internet Explorer?
Software updates can sometimes reset browser add-on preferences or introduce compatibility bugs with legacy browsers like Internet Explorer, which prevents the viewing plugin from loading correctly when you click an attachment.
How can I tell if the issue is my browser or the PDF file itself?
Try downloading a non-PDF file (like a Word document or an image) from your email. If that file downloads successfully, the issue is specifically isolated to how your browser handles PDF extensions.
Will switching to another web browser fix this issue?
Yes. Modern web browsers like Google Chrome, Mozilla Firefox, and Microsoft Edge feature native, built-in PDF viewers that do not rely on external plugins, making them significantly more reliable for opening PDF attachments.
How do I force Internet Explorer to save the PDF instead of opening it?
You can right-click the email attachment link and select 'Save target as...'. This action bypasses the browser's PDF viewer completely and prompts a standard dialog box to save the file directly to your local hard drive.
