I have downloaded the Lightroom 6.5 update installer. It installed fine on my Mac Pro (late 2013) running OS X 10.11.3.
It will not install on my MacBook Pro (mid 2015) that is also running OS X 10.11.3.
Here are screen shots of the error messages that I get:
There must be some obscure file(s) that are making my laptop think that the update is not applicable.
Would appreciate any assistance.
What version of LR do you already have on the computer?
The LR 6.5 installer is just a patch and expect LR 6.0 to LR 6.4 to already be on the computer. If you don't have LR on your computer then install LR 6.0 first then use the 6.5 patch.
Thanks for your reply.
I had Lightroom CC 2015.4 installed.
I resolved the problem by uninstalling Lightroom, reinstalling Lightroom (CC 2015) via the Creative Cloud panel, and then installing the separately downloaded Lightroom 6.5 patch. This time the patch correctly installed.
