I have been opening HEIC files with no trouble until tonight. Now it says it cannot be opened
Last time this happened, Adobe updated my software and it fixed the problem even though my software says it is up to date. What is up? I tried rebooting my computer and updated everything I can find to update to no avail.
I tried reinstalling HEVC app - no improvement. Though when I try to install the HEIF image extensions app it just says 'open' it does not appear anywhere in my list of installed apps so I cannot uninstall it to try again. Very frustrating. When I open that app it appears to be just a stand alone app that lets me open files inside the app itself - it does not seem to facilitate opening the files inside Adobe Photoshop Elements 2021. Help.
I've just paid closer attention to the title of your post. I have no experience whatsoever with Windows 365 so cannot help you any further. I've never heard of anyone using Elements with that Cloud service.
