Question: When I try to open a .pdf file, I get the error, The document filename.pdf could not be opened. Acrobat cannot open files in the Adobe PDF document format. But I can open the document if I open Acrobat and then open file through Acrobat. I'm using Acrobat Pro 9.Answer:
If you receive that error, then it means it's wrong associated or the file is corrupted, but I believe it's a simple association error. Locate the file then right click it and choose Open With. From the dialog window that will open, choose Adobe Reader or Adobe Acrobat and accept the changes. You also have to tick the option to always open the file using one of the selected PDF applications and then it should open correctly. If you still have issues, reinstall/repair the applications on your computer.
