PMDG Crew:

 

I searched for this on the support site first with keywords of 'uninstall' and 'deactivate' and didn't get any results.  Weird.

 

What is the proper procedure to remove the 777 entirely if I have the 300 expansion?

 

I was thinking:

 

1. Log into FSX and deactivate the -300 and the -200 base.

2. Uninstall the -300 from the Windows control panel, then the -200.

 

Make sense?

 

No opinions, would prefer real experience or a PMDG staffer.

Usually, the best course of action is the opposite order in which they were installed. That is the case here. Using the license return features, as you mentioned, will also help to speed up the process for everyone involved.
