No the patch will not auto run. To install GWX this is what you have to do:
1. Have a CLEAN installation of SH3
2. Patch it to 1.4 (just run the patch and point to the correct folder)
3. Install GWX (run the GWX.exe and again point in the correct folder)
4. Install the Dec-23 update (you can get it from the link in my signature)
5. You're ready to do
For the update you need to
1. Extract it to C\Program Files\Ubisoft\SH3\MODS
2. Run JSGME from C\Program Files\Ubisoft\SH3 and enable it
3. Enable whatever other mod you like
4. Enough of all this!!! Go and sink someone now
