Download OLYMPUS Viewer 3 Software

Olympus makes its ORF RAW file format viewer software available as a free download, but require that you provide your camera’s serial number before getting the app. I have no idea why this is the case considering the application is only useful if you have .ORF files and those files are only created by Olmpus cameras. There are multiple scenarios where you would want the app and not have the serial number… Say if you sent your RAW files to someone else and they didn’t already have the app, or you were at work and your camera was at home.

The good news is that serial number validation is all client side and the algorithm is quite simple. You can just use any 9 digit number and you can download the viewer software. Even with my camera miles away I was able to download the app.
