I just had a hard drive fizzle and so I wanted to re-install Lightroom 6 but I got a message that it could not find lightroom 5 anywhere.
That's because I hadn't installed it. I originally purchased 5, then upgraded to 6. On the new drive I was just trying to install the upgrade of 6 without installing 5 first (you know, 'clean' install).
Is a clean installation possible? How? Or do I have to install 5 first and then upgrade to 6?
Never mind, read the install prompts more carefully. When it can't find the full installed version you select which one you had purchased from a dropdown list and enter the appropriate serial number. Then away it goes.
