1st You buy it. Then you download it.
1st You install the trial of Creative Cloud - use it for 30 days and then convert it to a 6.0 License.
It sounds like you haven't purchased Lightroom 6 yet so you cannot download it.
I must have not explained my question correctly.
I OWN Lightroom 5 stand alone and several other Adobe products.
When I start Lightroom it offers to update to Lightroom 5.7 build 991162, and after installing the update software it does not install the promised version.
In the past updates to Lightroom 5 were very simple and didn't ask for the installation of Creative Cloud. My question is how to update to the offered version, because the automatic process is not working.
" I get an offering to update to build 991162 which includes facial recognition, panorama, HDR, etc."
This is a paid upgrade - not a continuation of Lightroom 5. Until you buy it or subscribe, you won't get it.
Most unfortunate and misleading from Adobe.
