Sorry to repeat an earlier post, but I'm not sure if you tried it and if it didn't work. 1. Do you have the Preview Pane enabled in File Explorer? If so, can you disable it temporarily to see if the problem goes away? On Windows 8, in Explorer go to the View tab, and if the "Preview Pane" button is pressed, un-press it. On Windows 7, towards the top-right (towards the left of the help icon) there's a "Show the preview pane" button; un-press it. 2. Make sure the following directories exist on your machine. If not, please create them: C:\Users\USERNAME\AppData\Local\Adobe\Acrobat\DC\ToolsSearchCacheAcro C:\Users\USERNAME\AppData\Local\Adobe\Acrobat\DC\ToolsSearchCacheRdr replace USERNAME with your user name. Does doing 1 and/or 2 resolve this issue?
