Unable to open or read a PDF
No PDF reader installed
Before moving onto the following sections, make sure you have a functional PDF reader program installed. As a quick test, users may click the Adobe PDF icon to the right. If you have a working PDF reader, an example PDF should open in a new window. If it doesn't, download Adobe Reader or try an alternative free PDF reader. If you don't want to install any programs, an online reader is your best solution.
Tip: Updating your PDF reader may resolve many basic issues. Always verify you have the latest version installed.
PDF is not recognizable
In some situations, the file extension Microsoft Windows uses to identify the file as a PDF may be stripped away when it is sent through e-mail. If the file does not end in .pdf, Microsoft Windows will not know how to open this file. To determine if this is your issue, follow the steps below.
- Save the PDF to your computer's desktop.
- Open your PDF reader. You should be able to find it in the All Programs list in the Start Menu. If you have Windows Vista or later, you can press the Windows key and search for your reader there.
- Drag the saved PDF from the computer desktop to the reader. If the file is valid, it should open with no problems.
File is corrupt
If the example PDF opened when you clicked the image above, but the other suggestion did not help, it is likely the PDF has been corrupted. Re-download the PDF or, if it's an attachment, request that the e-mail be sent again. There are also some software utilities that can "fix" a corrupted PDF, though none we fully recommend at the time of this writing. These utilities may be found by doing a Google search.
Note: If the PDF is corrupt, the PDF Reader will still open a blank window. You may also see a warning or error message stating the PDF cannot be opened.
