OK, SeriousSpy
-gonna be
honest here: What I replied quickly is what I know so far. I would recommend to wait for one of the actual makers of this pack to chime in and reply as well.
My install order:
Copied my complete ModAct 5.3 install over. (Can also be a clean IL-2 1946 install. Read the readme of CUP and make necessary conf.ini setting changes as per readme in Mods section of conf.ini at the very bottom.)
Deleted the #SAS folder in there.
Deleted SFS auto
Deleted JSGME folder.
Downloaded MA 5.3 again including flyables and the other two download exes (updates) and installed, mean,
pointed it to the new place of my intended CUP install....that one is important!
No jsgme stuff yet activated.
Then extracted each CUP folder into a parent folder which held all CUP parts.
Started with the map section and cut out and pasted all of the CUP segments into my new MA 5.3 install.
Clicked "yes to all" if asked to overwrite.
Then I activated the cup parts I wanted, And all the Jet War elements I wanted, and the WAW elements I wanted, via JSGME exe.
Like here:
Then I opened the Exe Selector and chose my wanted segment, e.g. WAR.
Checked my RAm settings as well, "Save settings", closed Selector. Started again and started the game.
Make sure to save settings first.
I am not a member of the CUP assembly modders, only a minor contributor, so this may or may not be the right way to do it, worked for me for sure.-
