Try another PDF file program, such as Foxit Reader, to see it it can open. If the same error occurs, the file is probably no good.

Could be you need the latest Adobe pdf file reader on your computer to open the files. Software can be such a PIA. Can also be because you are using firefox 8, a real old version of the browser. Update the browser!

May be the file is actually damaged, or may be your PDF Reader is actually damaged.
First try to download the PDF file from different source(s) and then try opening that file.
If it doesn't work, go for different PDF Readers. Like you may try the Adobe Reader or Foxit Reader to open that file.

1. Download Adobe Reader 10.0 here
2. Download Foxit Reader 4.3 here

It just, no application can open that file so windows is suggesting to search for application to open/run that kind of files. Say example you have pdf file and you don't have adobe reader or application that can open pdf format it will flag that kind of message for you to be able to view/run it.

Hope it helps.

In Internet Explorer, when you click on a link to a pdf file,
you get the error message “Adobe Reader could not open ‘filename.fdf’ because it is either not a supported file type or because the file has been corrupted.”


This error is due to an issue with Adobe Acrobat viewing PDF files in a web browser.
Try the following:

1. Open Internet Explorer, go to Tools -> Internet Options and on the General tab to erase all temporary files, cookies and history data.
2. Under Internet Explorer -> Tools -> Internet Options, on the General tab click on Settings and make sure you select the option “Automatically” for checking for newer versions of the stored pages. Then attempt to open the PDC file again.
3. If solutions 1 and 2 do not work then uninstall Adobe Acrobat, then reinstall it again.
It seems that Acrobat 6 is more prone to this error so upgrading to Acrobat 7 may solve the problem.

All d best.

Any furthur help feel free to ask me again i will be more than happy to assist you.

if you get this error message when you try to open a particular file. the problem could probably be in the .pdf file and not the software. if this is not the case, uninstall adobe reader completely and reinstall it. if this docent work. download the latest version of adobe reader from the adobe site and try installing it again.
