We have 2 issues with our Acrobat XI Std v11.0.18.

• #1 the PDF files on the desktop are converting the file from the normal Adobe icon to thumbnails (preview of first page).  I went into preferences-general and I do not see the option to disable or enable PDF thumbnail previews for windows explorer.  Please help!
• #2 I'm not sure if this is related to the issue but when you click to open a PDF Acrobat opens but does not display an image.  If you close the PDF and reopen it, it displays the PDF. Please help!

1) This by design. Later versions of Acrobat (SUBSCRIPTION VERSION ONLY) have the option to turn this off (for new files only).

2) What do you see instead, that first time?

1)  So in my licensed version I can not turn this off and that is why I dont have enable PDF thumbnail previews for windows explorer?  Is this new for XI Standard

2) Just a blank view as if you were to open adobe via a shortcut or executable.

1) Not in the old Acrobat XI. It's a feature of the current version Acrobat DC, subscription ONLY (not permanent license).

2) So, do you have all the other window stuff around it? What does It say across the title bar of the window, in full?
