I can't open CR2 files from my Canon EOS Rebel XSI. I get the warning "Photoshop cannot open this file. If you are attempting to open a raw file from a digital camera, make sure you have the latest Camera Raw update installed via > Help > Updates."
So I go to Help >Updates and update, but then get the warning that "Some components of the following products could not be updated." Listed is the PS icon and a plugin icon.
I have Lightroom and PS. It used to work before in PS. I don't know what is happening now but it is really holding me up.
It is likely that your Canon's CR2 files require a newer version of ACR (Adobe Camera RAW) module, than you have.
There are two choices for me:
I can Move your post to the ACR Forum, or to the Photoshop Forum. As you are using Ps, and that IS a very active forum, dealing with a lot of ACR issues. I will Move it there. Your links and any e-mail subscriptions will follow perfectly.
