I am trying to install the KMDF toaster example on a WIN2K3 system. I
am running a checked version of the OS.

I'm getting the following message in \Windows\wdf01000Inst.log

Wdf01000 Setup cannont update a checked (debug) system with a free
(retail) version of wdf01000, or vice versa.

Question: I can only see one version of the wdf01000 coinstaller. Is
there a checked version somewhere?? Can KMDF be used on a checked
version of an OS.

Thanks,
kjmt

There is no checked version of KMDF 1.0. A free version of KMDF cannot be
installed on a checked build. The coinstaller internally uses "Windows
update" technology to install the KMDF runtime on your machine, and that
doesn't allow build type mismatch.

With the next release (soon to be released KMDF 1.1 with Win2K support) will
have a checked version of KMDF.

For now you can do the following:

1) Use a free build of the OS.
2) Install KMDF 1.0. with your driver
3) Then replace wdf01000.sys and wdfldr.sys from the system32\drivers
directory with the debug version of runtime provided in the
KMDF10\bin\debug\ directory.
