For all VIXIA cameras, Canon claims Windows 7 support BUT: "PIXELA ImageMixer 3SE is not supported by Windows 7 at this time"

even though it installs and launches the camera monitor.

The system still seems my camera as a Mass Storage USB device, but refuses to mount it....

Removing Pixela and rebooting, the device mgr now shows "Video Camera" rather than "USB Mass Sotrage Device," but it still can't mount or even eject it

No issues with my HG10 and HG21 camcorders in Windows 7 Ultimate 64Bit on my end...Pixela Image Mixer 3 SE Ver.3 program working fine thus far, also HG10 and 21 camcorder's are seen and identified as Canon device's in 7 as well...

*sigh* annoying -- also Win7-64 but no luck even after reboot

You'll have to manually update your motherboard chipset drivers with ones direct from Intel/AMD. I was having the same problem until I updated the drivers. Now transfer does work as before, but the app is so slow it's unusable. Pixela is supposedly working on the problem.

I'm thinking about just using Adobe Bridge to manage my video files instead... has anyone had luck with that?
