How do I restore ACR ACR 6.5 6.6?

I have a Windows 7 PC and other than uninstalling and reinstalling my all of the Creative Suite, I do not see how just uninstall the update (ACR 6.6) that makes me unable to access my Canon 5 d Mark II RAW files.  Any suggestions?

Everything worked fine until ACR 6.6 install later on Windows 7 (CS 5 Production Premium) machine. Bridge/Photoshop can read is no longer my Canon 5 d Mark II RAW files, but works well with old files Canon camera RAW, TIF, jpegs. How do I just ACR 6.6 uninstalling and reinstalling ACR 6.5 without doing anything else? Thank you.

The two paths you listed are the same that I have for Photoshop CS5 on my Windows 7 Professional 64 bit PC.  I got Photoshop CS5 installed on my laptop that has the same operating system under my desk and I just copied the file from ACR 6.5 Camera Raw.8bi paths of program files and program (x 86) File Format and paste in the same place for my office.  The Office had ACR 6.5 instead of ACR 6.6 Release Candidate.

I read a post somewhere where someone extract the Camera Raw.8bi of the 'Camera_Raw_6_5_Updater' files you download from Adobe.  The files are both files "2_1.zip assets" which are located in a folder of "Payloads" in the Updater folder.

Camera_Raw_6_5_Updater > payloads > the best two records have "Assets2_1.zip files (a folder has x 64 in the name, and the other does not work and is the (x 86)).".  Copy the Asset2_1.zip files in two different (one for the path of the program files) and folders to the path of the program (x 86).  These are zip files, then right-click on it and extract all the files.  The extracted file is named 1002 and 1003 - these should be in different folders, as you will rename them to CameraRaw.8bi - this, right-click and rename.  The larger of the two is in the Program Files path the other in the path of the program (x 86).

I did this because I could just copy from my other computer - Hope is working for you.
