I have LR version 3.6 that I purchased years ago. I cant update it.( says I am up to date) Do you have to be in the cloud in order to receive updates? Also I have PS CS5 are there updates for that?
Lightroom 3.6 was the last update for Lightroom 3. You are up to date as far as Lightroom 3 is concerned. If you want a newer version then you can purchase Lightroom 6, which is the current version. Photoshop CS5 has long gone into the "archives" and is no longer being updated. If you don't want to upgrade your software then you can use the DNG converter if your issue is needing support for raw images.
The best alternative to get the actual versions of Lightroom and Photoshop is the Creative Cloud Photography plan for 9,99$ per month.
If you don't want the Creative Cloud version you only can buy a upgrade of Lightroom (version 6) as a perpetual license.
