Updating Camera RAW Plug-In

I have PSE 12 and bought a new camera - Canon 7d mark ii - I believe I need Camera Raw Plug-In 8.7 for PSE to read my RAW files, however, I can't find the download. I did, however, download and installed Camera Raw 11.4.1- but when I go back into PSE, and look at what Plug-In its using, it still says version 8.5.0.236. Help! I have about 1,000 wedding pictures I need to sort through and edit!
