My guess is that DPP 4 doesn't work with 40D files. I believe the only apsc body it works with it the 7DII.
It works with lots of APS-C cameras, but not the 40D. In fact, just about every one that was released after the 40D, although finding a single complete list of supported cameras is (apparently) impossible.
This is from the 4.3.0:
