Interesting how this problem seems universal, and has been going on at least since the Office 2003/Vista days; yet Microsoft has yet to recognize that it exists. When clicking on a .DOCX document to open Microsoft Word, I have received the "There is a
problem sending the command to the program" for years; happens regardless of the computer, operating system or Word version. Clicking on a document icon opens Word; but, then Word cannot open the document unless the user takes additional steps. Don't bother
attempting to jump through the ridiculous steps that techies throw at you. I mean, clicking on an icon should open the document; kind of basic, don't you think? Why should a user have to jump through complex fixes in attempt to get an application to do one
of its most basic functions: opening a document? The only solution is to just live with it, because Microsoft is obviously not going to do anything about it. Once you get the "You can't open a Word document by clicking on the icon unless Word is already open"
notice, just close the alert, and then click on the icon again. If Word is open, you will be able to open a Word document by clicking on its icon.
