PDF opening error

The error reads: "Adobe Reader could not open … 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)."

 

This PDF was saved by myself to my desktop this morning. Unfortunately now it does not want to open. It was not emailed. The size of the pdf is 46.6Kb. I have uninstalled and reinstalled Acrobat Reader DC and restarted my computed..no luck. This is also the ONLY file that is not working out of the 3 I saved early.

 

I've looked though the threads but it seems the only way to retrieve this pdf is to be somewhat familiar with coding, which I am not. Am I just SOL with all the data I inputted in there? What caused this?

Hi Brittbritt

 

We are sorry for the trouble. As described you are getting the error 'Adobe Reader could not open … 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)'

 

Usually the conflict stems from how those PDFs were created and that is where most of the problems come from. It could be created from an older version of Acrobat, someone could have used an online converter that produce a bad copy of the PDF, the converter tools on Acrobat could be damaged in some way.

 

What is the version of the Adobe Acrobat Reader you are using? To check the version go to Help > About Adobe Acrobat Reader and make sure you have the latest version of Adobe Acrobat Reader installed. Go to Help > Check for Updates.
For more informtion, please take alook at the help page https://www.adobe.com/devnet-docs/acrobatetk/tools/ReleaseNotesDC/index.html

I am using the most updated version. Is there any further guidance on second solution? Perhaps a step by step guide of where I'm inputting the code at?
