Thank's Markoz will do as instructed and hope for the best.  Do either of the old versions need to be deleted or am I just upgrading? Thanks Ged.

Completely uninstall the previous versions. And...

1) Make sure the [FSX]\SimObjects\Airplanes\CS_B737-100 and CS_B737-200 folders are deleted. You will need to add any 3rd party liveries again so their texture.xxx folders might still be there.
2) Also make sure that the [FSX]\Captain_Sim\737 is deleted.

Once that's done, you are ready to install everything, as explained in my previous reply. ;)
