You can install it anywhere you want.
You Need to add POTC to the game list in the program and set it.
Now a d3d8.dll (I believe ist called that) file is made in you potc Installation.
If you dont set anything only the global presets are used and it uses dx9 now.
There is also an Option to have for example more AA etc. You first Need to set the right plugin in the Pipeline tab and after that Change the Settings.
When I have some time again I will try to post some of the dlls and required files to test with different Settings. But you can also try yourself ofc.
If you see the message added during the start of the game you will have added the game right.
