PDF file won't open with double click

This has been frustrating, but after many trys the following worked for me because I have two versions on my computer Acrobat DC and just Reader DC.  

I right clicked, scrolled dow to properties and under general selected change under opens with. Selected Acrobat DC and now it works

I suddenly started having the same problem.  Realized the only thing I changed was my mouse pointer speed.  I slowed it down and double clicking an attachment from Outlook worked.

Disable preview pane in windows explorer, change to detail pane and the issue should go away. Windows 10 this works anyways.

as of 06.18.18 none of my PDFs open on Acrobat DC... wtf Adobe???? don't see see all these ^^^^^ comments????

This answer ("Select a pdf, cmd+i to bring up info. Within that dialog, their should be an Open With (Open all & open this file") absolutely DOES NOT work!!!  Adobe Reader is set as the default app to open pdfs.  This is a real problem that just started yesterday after working just fine for as long as I've ever used Adobe Acrobat - Please Adobe get your act together and tell us how to solve this problem - your solution is not the answer.

Operating System:  Mac OSx 10.12.6

Adobe Acrobat 2017.012.20098

I had exactly this with Acrobat X which I prefer. I could no longer drag a PDF on top of the dock icon to open. Double clicking launched Acrobat X but didn't open the document. File>Open worked. Clicking the X to close didn't. File Close though closed it. Installed the demo of Acrobat DC. All is fine.

Suppose I'll have to find my original Acrobat X but that was a while back.

The cascade trick didn't change anything for Acrobat X.

On Mac: Window > Cascade worked for me as well. If you close it now in that state, it won't happen any more. Thank you for posting this.

I have a similar problem with Acrobat DC, which is part of Creative Cloud. About once a week I run into a situation where I cannot open ANY PDF file... whether I double click the file or try to "Open" from within the Acrobat application.  To solve this, I uninstall Acrobat DC, and then reinstall it...which is a time-consuming interruption to my workflow.  I assume there must be an issue (perhaps a compatibility conflict) with the Acrobat software that needs to be addressed by Adobe.  I never had this problem until Creative Cloud updated me to Acrobat DC.

I do not have cmd key- This is Windows PC
