installation problem, minidriver in vista

I am new to device driver technology.

I am having a problem in installing the minidriver sample code which
is shipped with vista in location “\WinDDK\6000\src\print\mini\mdw\canon10v”.
After building it for vista environment, when i try to install it with the help of inf file,
i got error message “Printer driver was not installed. Operation could
not be completed”.
Anybody having idea regarding the same. Or if any change in build procedure so that i can successfully install minidriver on Vista Machine. Others components provided in print
folders can be installed successfully. I am only facing problem in installing minidriver.

Please reply.
thanks in advance for kind effort
