There was a problem starting PhotoViewer.dll

Windows 7

There was a problem starting C:\Program Files\Windows Photo Gallery\PhotoViewer.dll

The specified module could not be found.

One solution (work around) to fix this change the default editor

HKEY_CLASSES_ROOT \ jpegfile \ shell \ edit \ command

You could use mspaint like this:

old value: %SystemRoot%\System32\rundll32.exe “%ProgramFiles%\Windows Photo Gallery\PhotoViewer.dll”, ImageView_Edit %1

new value: “%windir%\system32\mspaint.exe” “%1”
