Yes, definitely install the DirectX v9.0c. It has library files that SH4 needs that are no longer in the "modern" DirectX versions. Microsoft will not let it overwrite the rest of the DirectX, but will allow it to add a couple of files needed for "backwards compatibility"...
As for the folder, I'm not certain what you are referring to about THEBERBSTER's instructions, but maybe you're looking at the folder of where to install the game to? With "modern" Windows, the "Program Files" folders are protected from user or "un-authorized" edits, such as what JSGME would do. In Windows XP, the OS didn't care, but now there is User Access Control (UAC) and other schemes to protect the computer from the User. When you go to install the game itself, change the path from "C:\Program Files (x86)\Ubisoft \Silent Hunter..." to something like "C:\Games \Ubisoft \Silent Hunter..." (or whatever you want to do for a path), and that way, you won't run afoul of the MS protection racket when you go to apply mods... You might also be looking at where THEBERBSTER had said to make a folder to download the mod into, and unzip it in that folder, then moving the parts you want from there into the MODS folder of your install? Be sure you don't have any double folders...
btw, you'll not find an easier mod to deal with than THEBERBSTER's GFO re-mix
here (first page of the thread).
