Windows 11: Can't Open PNG Files? Here's How to Fix It
If you can’t open PNG files in Windows 11, the root cause is usually a corrupted PNG file. Typically, you’ll see an error message like “The specified procedure could not be found” or “Sorry, we don’t accept this format.” It’s also possible that nothing happens when you try to open the PNG file.
File corruption usually occurs due to an interrupted download over the Internet or a file transfer from one location to another. It is rarely the result of something you did wrong.
Other common reasons why a Windows 11 computer cannot open PNG files include an operating system glitch or using the wrong app to view the image.
