Fix File Cannot Be Found Error When Opening PDF Links in Acrobat
Question details
Users experience intermittent errors where opening a PDF hyperlink from an email results in a message stating the file cannot be found, though it often works on a second attempt.

- Product
- Adobe Acrobat / Adobe Reader
- Device & OS
- not provided
- Scenario
- Opening a PDF document via a hyperlink directly from an email client.
- Observed behavior
- Adobe Acrobat or Reader displays an error message stating the file cannot be found. This issue is often intermittent and may resolve if the link is clicked a second time.
Ensure your internet connection is stable and that your email client has fully synced and downloaded attachments before attempting to open any links.
Download the PDF and Open it Locally
Saving the file to your local drive bypasses temporary folder restrictions and email security blocks.
Email clients often save clicked hyperlink files into hidden temporary directories. Sometimes, Acrobat attempts to open the file before the download to this temporary folder is fully complete, resulting in the 'File Cannot Be Found' error.
Right-click the PDF hyperlink or attachment in your email and select 'Save As' or 'Download'.
Save the PDF file to an easily accessible local folder, such as your Desktop or Documents.
Launch your PDF reader, go to File > Open, and select the newly downloaded PDF document.
Install the Latest Application Updates
Updating the software ensures any known bugs related to hyperlink handling are patched.
Test by Disabling Protected Mode and Enhanced Security
Acrobat's strict security settings can sometimes block files opened from temporary email directories.
Use WPS Office to Seamlessly Open and Edit PDFs

Frequently Asked Questions
Why does the PDF link work on the second try?
When you click an email link the first time, the email client downloads the file to a temporary folder. If your PDF viewer opens before the background download completes, it triggers a 'File Cannot Be Found' error. The second click usually succeeds because the file is already fully downloaded.
Does disabling Enhanced Security permanently fix the issue?
No, it is strictly a troubleshooting step. Permanently disabling Enhanced Security leaves your computer vulnerable to malicious code hidden in PDFs. It is safer to download the file locally rather than keeping security features permanently turned off.
Can I change my default PDF viewer to fix this hyperlink error?
Yes, sometimes the error is specific to how a particular PDF application handles temporary email files. Switching your default PDF viewer to a lightweight and compatible alternative like WPS Office can resolve intermittent hyperlink opening issues.
