The develop module is disabled when the LR subscription isn't active. This may mean either your 30 day trial is expired, or you haven't yet signed in to your Adobe account to activate the trial.
This is is often a bit confusing. LR6 is not a subscription version, but the trial version behaves like LR CC (which IS the subscription version) until you enter a valid LR6 key. So, for the trial period, you're essentially using LR CC.
thanks for your replies. what's strange is that I did have a 30 day trial membership in April for LR5 and found the plug-in for HDR confusing ... so I waited for LR6. So Adobe is still looking at my "expired" 30 day free trial last April but I was looking to start a new free trial. Not possible?
Sorry You could only try it for 30 days.
To Buy Lighroom 6 Go to
Select Lightroom "Buy" Upgrade from Lightroom 5
I have already downloaded lightroom CC but I'm dissatisfied with your reply about the free trial. I tried LR5 in April and didn't like it enough to buy. The deficiency back then (HDR) has been corrected so I would like to try the different version program (LR6/CC) now. why is that considered the same free trial? doesn't make sense. Is my only choice to try now by purchasing a month to month subscription? If that's the case, that's not very consumer friendly.
You are right, that isn't very consumer friendly. The Lightroom 6 trial version should be a separate trial, but I have read of others who have experienced the same issue you are experiencing. Sorry, but I don't have an answer for you.
