Apply next steps...
< Navigate to the location with the corrupted PDF file. Right-click on it and select "Rename." Type any other file name and hit "Enter." Sometimes, a simple rename can troubleshoot corrupt PDFs.
< Make sure your Adobe Reader is in working condition. Open any other PDF files on your hard drive to make sure the problem is not originating from your Adobe Reader. If it does, reinstall Reader from Adobe's website for free.
< Update Adobe Reader. Launch Adobe Reader from the Start menu under "All Programs." Click on the "Help" tab and select "Check for Updates..." Follow the on-screen prompts to complete installing the updates. Try re-opening the PDF file.
