Question

unable to open pdf

Jun 12, 2015 11:04PM PDT

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

As Bob said, it could be that somehow the files got corrupted. Then, for old files (that were being referenced for years already), get the uncorrupted version from the backup. For new files (recently downloaded or created) download a new copy or create them again.
However, if all these files open correctly on your own PC, something is wrong with your customers PC. Then fix that.
