It's a problem with the
texture.cfg, and not missing .DDS files. See attached image.
Copy the texture.cfg from the CS_B777F-II_GE110B1\texture.CS.2019 folder, and paste it in the texture.
x folder for FedEx, making sure to overwrite the texture.cfg that was placed there by the ACE.
Content of the texture.cfg placed by ACE:
[fltsim]
fallback.1=..\texture
fallback.2=..\..\CS_B777F\texture
fallback.3=..\..\CS_B777-200ER_GE\texture
fallback.4=..\..\CS_B777-200ER_GE\texture\night
fallback.5=..\..\CS_B777-200ER_GE\texture\spec
fallback.6=..\..\CS_B777-200ER_GE\texture\bump
Content of the texture.cfg placed from the texture.CS.2019 folder:
[fltsim]
fallback.1=..\..\CS_B777F-II_GE110B1\texture //general F dif/spec/bump/lm
fallback.2=..\..\CS_B777-200LR-II_GE110B1\texture //LR wings, 110 engines dif/spec/bump
fallback.3=..\..\CS_B777-200ER-II_GE90B\texture.CS.2019 //CS general
fallback.4=..\..\CS_B777-200ER-II_GE90B\texture //general, general 200ER
fallback.5=..\..\CS_B777-200ER-II_GE90B\texture\night //general night
fallback.6=..\..\CS_B777-200ER-II_GE90B\texture\spec //general spec
fallback.7=..\..\CS_B777-200ER-II_GE90B\texture\bump //general bump
fallback.8=..\..\..\..\Scenery\Global\texture
As you can see, the the texture.cfg from the ACE, is pointing to the CS 777F 32bit version for FSX/SE/P3Dv3.
A bug with the ACE for the 777II Freighter?
