I have licenced LR5 and LR6 and am now building a new PC. How do I install LR6 on it using my licence code?
On the old PC sign-out from the Help menu. Use the link below. Install LR6.0 first and licence with your serial number.
Then download the update LR6.5.1
It is usually straightforward to move to a new computer. See if this link and video tutorial helps:
