... another couple of things l02turner, when you go to run the v1.4 update, your game has to be stock. The folder has to be write-enabled, and you have to run the patch as administrator.
So, with a fresh, clean install - do NOT play it. Go into the game folder (preferably NOT in a Program Files folder, else Windows will frustrate modding efforst). Once you see the "Data" folder and the SH4.exe file in the game folder, press the <Ctrl> key, and while holding it down, press the <A> key. That should select all of the files in the folder. Now right-click anywhere in the selection area, and on the resultant 'context menu', choose "Properties" at the bottom of the list with a left-click. It will open a dialog with the "General" tab viewable. In the bottom section of that first tab is the "Attributes" section. Notice that "Read-only" probably has a "partial" check mark in it, in that it is not a 'clear' box, but not a fully darkened check mark either. Click in that box, and it will clear the check mark. OK your way out. If the box is empty, do not put a check mark in there.
I cannot remember if I ran my patch file from inside the game folder before or not, but you might try that. It seems to me though, that it follows the Windows Registry entry, though I am not certain... Anyway, from the patch executable file, select it and right-click it to bring up the same 'context menu' as before, only this time, up near the top is "Run as administrator". Left-click on that, and it should run with full authority. I do not remember the dialogs, if there are any, for pointing at the install and such, but you do have to run it as administrator...
btw - the v1.4 update will NOT run on a Steam install.
