WeidU Technical question for a manual installation with Big World Fixpack

So i am planning to mod BGEE2.3+SoD doing it manually :

1/ Unpack all the mods i am wishing to install in the game folder (without installing them)
2/ Run the Big world Fixpack (in order to apply the needed fixes on the unpacked mods)
3/ Then install manually each mod

The SCS mod comes with the usual SCS folder, a "stratagem.bat" file instead of the more common setup-stratagem.exe and a WeiDU.exe.

Big World Fixpack also comes with a weiDU.exe (and this the problem for me), along with two .bat files (_ApplyPatches.bat which i am supposed to run in order to apply the fixes and BiG World Fixpack.bat)

As i am going to unpack them both (and many other mods too), one of the weiDU.exe is going to be overwritten by the other. Is it a problem ?


I found in the SCS readme :

"...you can bypass the auto-installer and go straight to the standard process in the usual way - just rename weidu.exe to setup-stratagems.exe and run it. On BG:EE, though, this needs to be done at the command line with --script-style bg2 added."

All this is beyond my actual capabilities. How do i do "this needs to be done at the command line with --script-style bg2 Added"

Is it relevant ?
What should i do ?
