Copy and paste MAW completely from the stock install, and then...
Name the Second install, to MAW advanced or something, then install the multicfs3 program by Martin Wright ( MW Graphics) and run it in the second install ..
The multicfs3 program creates the pathway for the second install..
Then you must create shortcuts from the Second install, to your desktop or where ever you want them..then run the CFS3 config in your second install..
You MUST rename the MAW .EXE shortcut in the second install to what ever name you placed in your second install..
If you leave the .EXE named as the first install it will open this, not you second Advanced install you have.. also, Remember MAW has two exe's one for campaign mode and one for standard mode..
Create your shortcuts In the second install, then move them where you want them to be for use..Desktop or folder
I have 13 different installs of CFS3., BOB, ETO/PTO, MAW And DPC Korea on my machine and they all run perfectly..
That is when I don't muck about it them..
