Windows 10: Photo viewer not opening photos, gives error message

Hi,

Having used the photo viewer for years, it's now not opening any jpegs.
I get the viewing screen, with the file name and this message underneath it.


Advice appreciated.

Unable to replace Photos app with Photo Viewer as default (10240).


I'm not making any headway on answers.Microsoft.com so I'm hoping the experts here can explain why I cannot replace the Photos app with Windows Photo Viewer as the default image viewer (in build 10240). From all outward appearances, it seems Windows Photo Viewer is unavailable.

The saga is explained in detailed words and colorful pictures here:

If that's too tl;dr for you, here are the bullet points:

• Windows Photo Viewer is never listed as an option when using "Open with".
• "Open with" lets you browse the disk and manually select the desired program. I navigated to "\Program Files\Windows Photo Viewer" but it contains no program there other than "Imaging Devices" (wrong). Choosing "PhotoViewer.dll" produces an error message.
• In Control Panel's "Default Program", Windows Photo Viewer is shown to be associated with TIF files and nothing else. Attempts to set JPG to use Windows Photo Viewer fail because, again, its program folder only contains "Imaging Devices" (and the dll).

In an attempt to fix this problem, I used the "nuclear option" and Reset the PC. After Windows 10 (TH1 10240) reinstalled itself, I still couldn't select Windows Photo Viewer to be the default image viewer.

Suggestions to fix this?

Right there in my first bullet point: "Windows Photo Viewer is never listed as an option when using "Open with".

That would work if Windows Photo Viewer were in the list but it is not.

For everyone's convenience, here's what I wrote on answers.microsoft.com:

1. If I right-click a photo and choose "Open with", Windows Photo Viewer is *not listed* (only Paint and Photos).
2. I select "Choose another app" followed by "More apps" it is still *not listed*.
3. If I continue and select "Look for another app on this PC", I can navigate to "C:\Program Files\Windows Photo Viewer". However it contains only one program called "ImagingDevices" and it is *not* an image viewer.
4. If I display "All files" instead of just "Programs" I can see "PhotoViewer.dll". However, selecting this item results in an error message indicating it cannot be used for displaying photos.

 

photos vs photo viewer


If I double click on a .tif file in File Explorer it opens in Photo Viewer whereas if I double click on a .jpg file it opens in Photos.
I much prefer using Photo Viewer because you can run a slide show from there & with a right click adjust the speed or duration to Fast, Medium or Slow.
However, using Photos. although you can also run a slideshow, there's no option to change the speed.
So, in Settings - Default Apps - Choose default application by file type I scroll to .jpg & discover that Photo Viewer is not on the list of possible apps.
Of course, scrolling down to .tif & it's already set to Photo Viewer.
How can I set .jpg to open in Photo Viewer just as it is with .tif ?
