Taken from the AOE community forums, there is a way of allowing you to use the warchiefs races in asian dynasties. Here is how it is done:
- Run Regedit, and navigate to HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Microsoft
Games (everything will be under here)
- Go to Age of Empires 3 Expansion Pack 2/1.0 in and copy the PID
- Go to Age of Empires 3 Expansion Pack/1.0, create a string value with the name of PID. For the value, use the one you copied
- Go to Age of Empires 3 Expansion Pack 2/1.0, and copy the value
- Go to Age of Empires 3 Expansion Pack/1.0, right-click and create a binary
value. Call it DigitalProductID and paste the copied value.
This will cause the asian dynasties to be your only executable (as all the WarChief files will now be copied over).
