I want to uninstall V4 and keep V5 but I have the old PMDG 737, the new PMDG 737 NGXU and 747 in V4.
I also have the new PMDG 737 NGXU and 747 in V5.
I don't know whether they are linked in any way.
Does anybody have any suggestions for the process of removing V4 completely without upsetting any PMDG plane installation?
