I'm gonna presume that by 'Grey Wolves' you mean GWX (it's much newer)
If you are, install it like this:
Delete any/all SH3 files from C\MyDocuments
Install a clean version of SH3 in C\Program Files\Ubisoft\SH3
Patch it to 1.4b
Copy the folder and paste it to whatever drive you want.
Rename the folder ‘GWX’.
Now install GWX
Now install GWX (v1.0 whatever)
Create a shortcut to the desktop..
Install the SH3Cmd 2.7 plus the SH3Cfg file
If your going to use multiple installs I’d suggest a separate install of SH3Cmdr for each plus an install of MultiSH3.
