30 days trial finished, i want to buy a LR5 but i subscribe to LR year plan, not sure if this is the right one or how and where should i buy the serial number as to use a LR. i paid 9.99 USD for year plan, but sitll i didnt get the serial number and can not use LR
There is no serial number for the creative cloud plan. You install the creative cloud application manager and sign in using your Adobe ID and password. Then you install Lightroom and Photoshop from the application manager. Adobe no longer sells Lightroom 5. If that is the very thing you want to purchase you will have to find it for sale from another reseller.
If you have the Subscription plan you don't need a serial number. You download the Creative Cloud desktop app and once installed and opened just Sign In using the same Adobe ID, email address and password, you used to buy the subscription. LR 5 will change to a full, non trial, version. you can also install LR 6, Photoshop CC 2014 or 2015 and Bridge.
