I'm trying to clean up my "C" drive. I have both LR 4 & 5 on it, and in addition, I do have a CC subscription. Can I safely get rid of LR4? (I think I'd like to keep 5, just in case I'm in a situation where the internet might not be available). And a related additional question, I have the OnOne suite, both 8 & 9 - same question - can I get rid of 8? If I do uninstall either or both of these, what pitfalls might I run into? Thanks!!
