If anyone can shed some light on why this keeps happening I would love to know. I have tried updating the adobe reader but that didn't do anything. This problem occurs so many times a day that Task Manager has now been pinned to the task bar for ease of access. Once I run the end task I can preview the Pdf files again. Initially this advice related to 32bit files but now works on the files listed below. Funnily every time I go to task manager there are always 2 occurrences of Adobe running. I have searched the net for a solution and the only thing I can find that tends to work is to open Task Manager and End task on the Adobe Acrobat background processes. Even with each new folder opened, then there are days where the pdf's preview every time with no issues. This can happen once a day or 50 times a day. If I open a new File Explorer window none of the Pdfs will preview. The issue I have is with the previewing of PDF files. Needless to say that I use File Explorer all day long. All scanned documents are renamed and then processed. I run a business that is 100% paperless and involves a lot of data entry. Adobe Acrobat Reader for Android is the free PDF viewer, editor and creator.

I don't know if it is an Abode or Microsoft issue but it is really frustrating. Download Adobe Reader - Acrobat Reader is the global standard for viewing, printing, and commenting PDF documents. I am hoping someone can help me with this current issue I am having.
