When I double-click a PDF file, Reader DC does not appear to start. Task Manager does not show it in the "Apps" list, but instead shows it twice in the Background processes list. It shows as "Adobe Acrobat Reader DC (32)". If I click "End task" on either process, both stop.
If I manually start Reader, then Task Manager shows it in the "Apps" list, and when I double-click a PDF file, it opens and displays the document normally. But if I close Reader, then when I double-click a PDF file, Reader does exactly as first described above. If I continue to double-click PDF files, 2 processes of Reader start for each file clicked and the processes appear in the "Background processes" list, but Reader doesn't open or display any documents.
I am running Adobe Acrobat Reader DC version 2018.011.20035 on Windows 8.1 Pro 64-bit.
I found another Question on the Forum related to this called "DC Reader only run as a background process", but it is only "Assumed Answered". I ran all the steps in the assumed answer. I ran the Adobe Cleaner Tool, restarted the PC, then downloaded and installed the Reader version given above. The problem still occurs. I see 1,162 people have viewed that "Assumed Answered" question - has anyone found a solution that works please?
Best regards,
Peter
