Good question, I guess I have the same problem and because of this mit Lightroom CC 2015.2.1 is awfully slow and hanging all the time. I have an octacore CPU with 16GB of RAM.
Where can I download the 64bit version?
Supposedly, CC 2015 autodetects the OS bit size and installs a 32 or 64 bit version of itself, but that's not working properly for me.
Yes teh same here. ;-)
I have jsut reinstalled LR CC 2015 and again only the 32bit Version.
If you have upgraded from LR 5, make sure you are running the correct version. LR 5 and LR6/2015 are side-by-side installs.
With LR 6 and cc2015, there is no 32-bit version; it is only 64-bit.
