Activation or lack of?

I have an odd issue that's occurring in FSX:SE, I have all of the FSX Pmdg addons, a boxed copy of FSX and The steam edition. I held off installing the steam edition due to reports of PMDG aircraft not working within the game. Upon reading that they are now supported within the steam edition - I did a full uninstall and re install of the steam edition, updates the SDK for sim connect and installed the 777. It seems odd but upon starting fsx:se I'm asked for the permissions for the 777, but no activation prompt window unlike the previous boxed edition I had installed. Starting up at Heathrow the 777 initialises and everything appears to be working as normal, no anomalies at all. The question is, is it possible that with a previous activated copy, the 777 doesn't require activation with steam or is this something I have missed by not reading the forums?

I believe that once it has been activated on FSX, the activation will carry across to FSX SE providing hardware hasn't changed.

Ahh brilliant thank you, thought I'd messed the installation up at some point.
