I recent got a new dslr camera the canon t5i (700D) when i try to open my raw files i get the message "could not complete your request because the file appears to be from a camera model which is not supported by the installed version of camera raw. Please visit the camera raw help documentation for additional information. I did that & it told me to auto update try updating from in photoshop which i try & it tells me my applications are up to date. It also told me to manually update download it & to let the adobe patch installer update it but i get the error message "error loading the updater workflow" when i try to run it. I am currently running adobe photoshop cs5 extended version 12.0.4 x64 for windows 7.
The problem is support for your camera was introduced in Photoshop CS6's ACR 7.4
You will either need to upgrade or use the DNG converter to convert those raws to DNG format which will open in CS5's 6.7 Adobe Camera Raw.
