install 4.0.3 about 4.0.2

Hi, I use UM 4.0.2 with the Denon MC6000
the new UM 4.0.3 , can you install about 4.0.2?
or should you remove UM 4.0.2
I want to use the Option to disable crossfader on Denon MC6000
sorry for my english.


Hi Tony,

you have to uninstall UM 4.0.2 first before installing UltraMixer 4.0.3

Hi Tobi,
thanks for the quick response.
