Just to clarify, this program only works with VERY few older Canon cameras. It does NOT work with the 5D IV, 5DS, 5DSR, 1DX II, 7D II, 6D II, T6i, T6s, T7, T7i, 77D, 80D, SL2, SL3, or any other newer Canon body. In fact the ONLY Canon bodies I have in my store that this program works with are a 50D, 70D, and 5D II.
I do use this on some older Canon bodies and it works fine on them. And I do have the latest May 2019 update.
The software at this link reads my 5DIII fine, that appears to be the midpoint of the range you've listed. Again, a "free" starter option if it should prove unsuccessful for a newer EOS model. The enclosed RTF indicates a freeware utility based on Canon's SDK 3.5 is needed for cameras based on the DIGIC6 processor and newer. Canon seems to be going out of their way to make sure the shutter count is not freely available; and rather, can be accessed only by Canon at a Canon Service Center.
