The Canon EOS 50D has been supported since Camera Raw 5.1
Which version Camera Raw do you currently have installed? Which version of Photoshop and/or Lightroom and/or Photoshop Elements?
I am using lightroom 4.3 and I installed camera raw 4.6 and it seems to be working fine. Is there a better/more recent version?
Just to make sure everyone is on the same page. You do realize that Lightroom has its own version of Camera Raw incorporated and does not need the Camera Raw plug-in that is necessary for Photoshop?
Thanks for the response. That's what I thought as well, however, when I connected my cf card from my Canon 50D Lightroom did not recognize my cr2 raw format. After the plugin, it did. Thanks, Mark

Installing the plug-in may have installed some missing profiles as well. But Lightroom does not use the Camera Raw plug-in. If you don't have Photoshop you can trash the plug-in and Lightroom will still work.
