Its a long time since I have used Adobe but now I don't appear to be able to do anything. I have a tree files as a PDF format. I cannot open them because the following error:  PDF file is not readable with Acrobat Reader.  I am using Acrobat reader 5.0
(I tried Acrobat Reader DC but that appears to be a professional users software and requires a subscription to use it).
Any suggestions how to fix PDF files?

Adobe Reader 5 is very old and unsafe! Adobe Reader DC is also a free product and can be download here https://get.adobe.com/reader/ (uncheck the optional offers before download, they aren't needed)


Only the PDF editor named Adobe Acrobat Pro or Adobe Acrobat Pro DC its a commercial product.

Windows or Mac? Do you try default Application Preview on Mac?

If memory serves, newer versions of Acrobat and other PDF makers can save files using a newer version of the PDF protocol. This might make them incompatible with older versions of Acrobat. So, if you are getting these PDF files from other people who are potentially using newer PDF makers, then that might be the reason. If so, then either using downloading and installing Acrobat Reader DC (which is free as noted by SleepyDude) or using some other newer third party PDF program (such as the one recommended by Allan) would likely solve the issue.
