Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Just something to add here - I get this same error. I think it has something to do with the Windows 8 Explorer preview window (to the right of the file list when you try to select a file in an attachment file select window or just browing my computer), because I get it every time I just single click on a file, and it then fails to show a preview. To further this theory, I also get strange errors about "Sorry, something went wrong and Word was unable to start. (24)" when SINGLE clicking on a word document, which also fails to show the preview. Does this help any of the experts out there tell us how to fix it?
