How to install and activate a former Lightroom 3 version?
Hello
Since one year I use Lightroom6 . Before that I had Lightroom 3 on my MAC.
Now I wanted give my former LR3 to my nice incl. the serial number. But she can not activate the LR3 serial number and I do not know how to de-activate it.
For my new LR6 I have a new Serial number.
Please where can I de-activate my former LR3 license. Thank you for a short help
Greetings
Emil
