I have been overseas for three years.  I have come back to a computer that is not up to date.
I updated my computer and am ready to reinstall my aircraft.

However,  I can not re-install my 777 Captain II because I am running P3DV5.

What do I do now?  I tried to install the version I have and it only gives options for P3DV4.

What is my solution besides someone telling me to go to Microsoft which I will not do. :(
