Adobe Acrobat won't open PDF files
Try opening the PDF in your web browser to test if it's corrupted, launch Acrobat in Safe Mode, or clear Acrobat's cache files.
Acrobat won't open PDFs because the file is corrupted, Acrobat's cache is broken, or a plugin is crashing it. Test in the browser first, try Safe Mode, and if that works, clear the cache.
