I'm having no problems with lightroom 6.3. should I upgrade to 6.4? looks like all the upgrades are for the cc users and those that use Nikon cameras. also, when I go the "help" header, and check for upgrades, the upgrade notification looks like it is just for lightroom cc 2015.4. no where is there a listing for 6.4. if I select the download will I be changed to lightroom cc?
LR cc 2015.4 and 6.4 are the exact same download and program. It is how you Sign In that makes it one or the other.
Yes you should update to 6.4.
