This is what I am getting when I try to open any PDF files,  "If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document." I have an Adobe PDF package, so don't know why it is not working

You need to use Adobe software. Your browser (such as Chrome or FireFox) can't do this. Download the PDF file, open it in Acrobat Reader.

I downloaded the file from Whatsapp. Please help!

I have the same problem but opening the downloaded file on Adobe Reader or Pro DC doesn't work. The person who filled in these files (forms) can open them on his laptop Adobe reader. So bizarre. Can anyone help?

Please show a screen shot which shows this message in the Acrobat/Reader window. (Show the whole window, not just the message). Also, if you download the PDF file you must DOWNLOAD it not use other tricks like print-to-PDF.

I am having this problem too. Can someone please help? Here is a screenshot. I followed all instructions to download the file, open Adobe Reader, then open the file. Others can open the same file successfully.

Ok, let's look at how you downloaded the file. What browser do you use, and what steps do you follow, step by step, to download the file?

[Scott5C47]

Interesting...I downloaded it again from a different browser and now it works fine.

I have the same problem. It seems to be a bug with Adobe PDF. I use both PDF reader and PDF pro updated to the latest version of CC and nothing. Same dumb message. I've seen threats everywhere so the probme is massive. What a waste.

How have you downloaded the PDF file?
