    photo viewer fix


    The problem with PhotoViewer opening with a print dialog instead of the image viewer was due to an incomplete registry key (missing "open" subkey). Executing the following .REG file solves this problem. No reboot needed.

    This works like charm nexus.

    Here is a zip file of .reg key for those that don't know how to make the registry key, Simply save the file to your desktop then extract the zip file & follow the prompts to add it to the registry.

    Excellent fix Nexus !

    Try to associate the desired image format with a BAT file containing the following code

    rundll32 "C:\Program Files\Windows Photo Viewer\PhotoViewer.dll"

    ~edit~

    I tested myself and nothing happens... no go !

    Thanks for the tip. Now knowing where to look, I inspected the following key on the Windows 10 machine.
    HKEY_CLASSES_ROOT\Applications\photoviewer.dll\shell
    It contained the "print" sub-key but was missing the all-important "open" sub-key.

    Unable to replace Photos app with Photo Viewer as default (10240).-photoviewer-registry-key.png

    I exported HKEY_CLASSES_ROOT\Applications\photoviewer.dll\shell from my Windows 8.1 machine to a REG file, compared it to the information you supplied and found it was essentially the same.

    I backed up the relevant key on the Windows 10 PC and imported the REG file. Long story short, "More apps" now shows "Windows Photo Viewer" as a potential replacement for Photos. I'm now able to easily set windows Photo Viewer as the default image viewer.

    thank you soo much for this! I was going nuts trying to figure this out! WPV worked great when I upgraded but couldn't find it on clean install. This did the trick!

    More than a year later & this thread is still helping folks.
    Just bought a new Win10 PC & got the photoviewer.dll to work once, by browsing to it, and then started getting the error message.
    Can not use this program to open this file, or some such thing.
    I copied the registry fix into a text file and changed the extension to .reg and applied it.
    All's good now.
    thanks to those that came before.

    The problem with PhotoViewer opening with a print dialog instead of the image viewer was due to an incomplete registry key (missing "open" subkey). Executing the following .REG file solves this problem. No reboot needed.

    This works like charm nexus.

    Here is a zip file of .reg key for those that don't know how to make the registry key, Simply save the file to your desktop then extract the zip file & follow the prompts to add it to the registry.

    I can't get anything to work as Win10 seems to have "locked" the defaults for Photos app. Nothing I do will allow me to set Photo Viewer as default or even uncheck .jpg for example as a file type with Photos as default app. Any suggestions would be appreciated!!
