Adobe is quite obviously run by tech geeks, for tech geeks. In contrast to Apple run by tech geeks but with the added buffer of a human interaction department to make sure things like this never make it out.
While *I* can look at this and see what's going on, you can bet your ass the VAST majority of users will be confused and CERTAINLY not know what to do for the best setup afterwards.
What this was telling me was the bottom 'Lightroom 5' was my current 5.4 version. Notice they don't even have the good sense to include the version numbers anywhere. Which wouldn't be a problem if they didn't do stupid stuff like we now see.
The top 'Lightroom 5' is the update, version 5.5. Up to this point I have never seen multiple instances, it simply says Update Pending for whatever is there. Again, no good sense here.
Then we have the genius of the Adobe team reverting BACK to version numbers when they said they were done (cc). Now instead of 'Photoshop CC' getting an update like has been done till now, we have the 2014 designations for most of the applications. First, STUPID versioning. What will the updates be called, 2014.1? Second, it's certainly not clear to the average user that this is an ALL NEW installation. You can bet most users will now have redundant, old versions hogging drive space. Hell I have seen photographers with 4 old versions still installed because they had no clue they were still there. Same with Lightroom.
CC was supposed to handle all this a LOT better. It boils down to shitty design by the Adobe staff. They need to REALLY look at how other companies handle things, like Apple or even Steam.
