Cannot Open Pictures - jpg file

[Chuck-Del]

Purchased a new computer usbing Windows 10 to replace my old windows 7 about 2 months ago.  I transferred all my files to include about 375 gig of photo albums.  Once tranferred, I was able to open all photo files and view each photo.

Not sure what happened, but my wife went in to view some photos and work on editing them only to find she could open the folder; see all the individual photo tiles; but could not open any individual photo.

I tried earlier today and discovered the same thing.  Here is what I get when I tried to click on an individual photo to open it:

                       C:\Users\cjz\Pictures\2017 Mexico Trip\May 25, 2017.jpg  Class Not Registered. 

Not sure what "class not registered" means.  Has anyone encountered this issue or does any one know what I need to do in order to open each photo???

Pobably your wife used a different way to open files. Now Please try :

In my case, I installed the following program to view photos/images on all my Windows 7, 8.1 and 10 computers and set it as default

Class Not Registered. 

Click on the tile/icon for the file with the second (usually the right) mouse-button, and choose "Open With".

Windows will display a list of programs that will handle a '.jpg' file.

Below, the list, there is a "choose a default program".

The "default" program is the program that will be launched to open the file whenever you "double-click" on the tile/icon.

There's no need to install any more programs to process that "class" of files -- namely: image files.

Somebody with access to your computer may have uninstalled the program that was the "default" program, thus "unregistering" that association.
