You must apply the DTM mod to a full install of Heat. I found that Heat
would
only do a full install if I selected install icon on desktop and install to
the
default directory under c:\program files\hasbro interactive etc. After this
I was
able to apply the noCDandupdate patch from the pits website and then the DTM
mod.
It is a pain is the rear but I find DTM well worth the effort.
Good Luck,
