The 7D Mark II has been supported in Adobe products, Lightroom 5.7 and Camera Raw 8.7 or newer, that were current as of Oct/Nov 2014. I think. I have that camera and have been using it with Adobe products for several years.
It is likely your software is several years old but cannot be updated without paying for a new version or updating your OS to allow it to host newer versions of software. Without knowing which software and OS and what version of each you're using, it's hard to be more specific about what to do.
