I just joined the Creative Cloud Photography plan. I have 64-bit Windows 8.1 system. However when I check the installed programs in Revo Uninstaller Pro, it shows that my Lightroom 6 is 32-bit. However for my old Lightroom 5.7.0, it shows that I have the 64-bit version.
How can I determine exactly which bit version of Lightroom I have installed? Shouldn't the Creative Cloud installer know that I have a 64-bit system and install the appropriate version?
For what it's worth, it's also showing 32-bit for Photoshop CC, Adobe Bridge, and Adobe Creative Cloud.
Help / System Info should tell what version of LR you're running. I don't think there is a 32-bit version of LR 6 so the Rev Uninstaller Pro is misinterpreting something.
You can also look at the Processes tab in Task Manager and see if Lightroom.exe has a (32 bit) next to it or not. Things without this designation are 64-bit.
