the Nero download from www.nero.com
is just Nero Burning Rom, not InCD.
if you want InCD you need to install it from a Nero installation CD (comes with your burner or you buy it), or you can download InCD from www.nero.com
and if it detects that you already have Nero installed on your system it will install InCD.
so if you just donwloaded the Nero 18.104.22.168 file and installed Nero, you don't
have InCD installed.
you should have no problem having Nero and DirectCD installed and working on the same system. (and Easy CD Creator too if you want it).
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
