Uriah,
If you are trying to install the Cross Channel Map from 352nd_Cross_Channel_Map.exe and want to do a manual install, copy the .exe file to a temporary working folder.
Run the .exe, pointing it to your temporary working folder.
As the .exe runs you'll see that it creates a folder called "MODS_CCM_Insert" as it is working. A batch file script runs which creates two other folders, "Missions" and "MODS" and then deletes the MODS_CCM_Insert folder.
You then will have one file and two folders in your temporary working folder -- the .exe file, Missions and MODS folders.
Copy the MODS folder to your game, overwriting what is in your existing MODS folder if you have one.
Copy the Missions folder to your game, overwriting what is in your existing Missions folder.
There should be no harm in overwriting the content of the two Missions and MODS folders since the installer only ADDs content, it does not delete or change anything already there, unless you already have the CCM installed. If you are concerned about overwriting either the MODS or Missions folder, simply copy or move the contents of what is in each folder now in your temporary working folder to the appropriate path in your game -- the MODS and Missions folders are there to map the installation path.
Then follow the instructions on locating your all.ini file and add the CCM line as instructed.
Hope this helps.
