I have an issue with Adobe Reader, the file preview in windows explorer stops working with the error "there is an issue with the preview handler". If you run a repair on Adobe the issue resolves itself, however after a few days the issue occurs again. I have tried reinstalling the software with the latest version, clearing temp files and stopping updates however the issue keeps occuring.
Go to "File">" Options">" Test Center">" Trust Center Settings">" Attachment Handling". Here, ensure that the "Turn off Attachment Preview" option is unchecked. Tap the "Attachment and Document Previewers" button and then check if the option that says "PDF Preview Handler" is ticked or enabled.
