Edit a raw file of 550d in Photoshop

Cannon 550d raw format suffix. RC2, which cannot be edited in Photoshop. Search for it online and update the camera raw.8bi file in the plug-ins \ file format directory. This involves the PS version and the Camera Raw version. The old PS on the machine does not seem to find the matching Camera Raw file. The final pairing is:

Photoshop cs5 + Camera Raw 6.2 update

However, my PS is green, and the installation file of Camera Raw 6.2 cannot be installed. I have an introduction on the Internet: the installation package is a zip file, there is a payloads folder named adobecameraraw6.0all-210510124504 (the 32-bit 64-bit is the one with x64 and has not been tried). There is a compressed assets2_1 file, decompress the package to change the name of the 1003 file to camera raw.8bi.

Start pH and you can edit RC2.
