RAW photos are not rotated automatically

[ChicagoGhost]

IMatch displays my RAW photos (CR2 files, which were shot in portrait mode) in the wrong orientation. They are displayed in landscape mode. JPG files are fine.
There are no sidecar files to these photos.
They are displayed in the correct orientation in Lightroom or Windows File Explorer.
It needs a lot of work to manually rotate them one by one.
Is there a setting to display them correctly, or a command to find all these photos, group them together, and apply the rotation to them all?

CR2 is a proprietary and undocumented file format.
Which camera and firmware version do you use?
Do you use WIC or LibRaw?

If you use WIC, try LibRaw ("Prefer photools.com RAW Processing" in Edit > Preferences > Application) and then force an update of affected files by selecting them in a File Window and pressing Shift+Ctrl+F5 > Force Update).
