One Photo Viewer for Windows 10


Pro ($2.99)

(Pro version is not available in all countries)

One Photo Viewer for Windows 7/8

Only free version. This installer also work in Windows 10 but you will get a warning when installing since I don’t pay for a trusted certificate for this installer, Windows really don’t like that. But you can install anyway by clicking on “more info” or something like that.
Get it from Microsoft Store if you run Windows 10.
