pdf files will not open in Acrobat Reader on pc

[Andrew31760283dney]

"There was an error opening this document. The file is damaged and could not be repaired." That is the error message when trying now to open downloaded pdf files in Acrobat Reader (64-bit latest version) on my pc with Windows 10. Older pdf files open fine. The problem files in question can be opened with Microsoft Edge browser, so the files appear to be ok. What is wrong, and what do I do to fix this??

Sorry to hear about the trouble caused. 

As confirmed, the file opens fine on the web browsers but not in the desktop application.

Also, if you haven't updated your application in a while, then 

Run this cleaner tool to remove the existing installer and application’s file traces:
