Are you using a windows or Mac computer?
Simply uninstall the version 6.2.1
Redownload Lightroom from step in the link.
Then install patch 6.1.1
Also refer link below as we are planning to restore many features from version 6.1.1 in our next update soon.
I am using Mac. One CANNOT just patch to 6.1.1, the page I referred to specifically says :
If you receive a message that says “This update is not applicable to you”, you’ve missed step 2. The base 2015.0/6.0 release must be installed before attempting to install the 2015.1.1/6.1.1 patch.
I tried it.
So I need 6.0. It is not on the page. I hope this is clear
I now see that the box at the top, which I thought was a header, in fact takes one to the 6.0 download. Sorry about that
The link in step two gived you the "setup.dmg" which is the base version 6.0
Did you downloaded and installed it?
