You may need to start an on-line chat session with Adobe Support Staff. As a work-around launch LR5 and click:
Help >> Updates
Install LR 5.7.1 and your 7d2 files will be supported.
Yes, I believe you are correct, I will likely have to chat direct.
Once I calm down I may attempt that.
Unfortunately when I try to update 5.6 it pushes me direct to CC.
Thank you Installing now- Provided me with a workaround for short term-
At least I can get my weekend images edited now. Thank you!
