Unable to open pdf

[Former Member]

My customer has recently encountered a problem when trying to open most of their pdfs that they have been referencing for years on their pc.  Reader has a popup box that says "Adobe Reader could not open 'file.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded

I have tried various programs to recover/restore/repair them, they all say the files aren't PDF files.  I have not paid for any recovery programs but would be willing to if they can demonstrate they can fix the problem first.

Thanks

f you use a PC, you can use software you already have on your computer to retrieve some of the content. Right-click on the corrupt file and choose ‘Open With’ and select the Notepad program that comes bundled with every copy of Windows. The resulting file will contain a lot of coding but within that coding you will see the content. This is perhaps a only really viable with text-only PDFs as when you are dealing with images and forms, Notepad will be swamped with coding and finding the text can be the proverbial needle in the haystack.

Hello Michael,

This issue is happening due to validity of Adobe reader rights. The server date and time and document creation date and time are conflicting.  Read the blog below.
