make sure there is only 1 version of ‘link.exe’ that is being pointed to by
the environment directories.
an old one will conflict with an updated one.

Interesting… Do you expect driver to create console application window and
“printf” into it? :wink:

For tracing from the driver use DbgPrint (or macro KdPrint). Also keep in
mind to call only kernel exported functions (printf is not exported by
ntoskrnl.exe).
