Works fine for me, I just downloaded and installed both of them to my PC. Perhaps the Canon site was down for a while. Try it again. The 24-70 mk II file is 17 MB, the 70-200 MK II file is 25 MB
OK, after 2X removing and reinstalling (from my 5DIII disk) and updating, I reinstalled from my 7D disk (4years old) updated that, and it works! No idea why that would be different.
You can go to the Canon site and download all the updaters for DPP and the rest of the software.That should get you updated to current versions. good luck
I've been having the exact same issue. My 70-200 f2.8 VII is OK but my 24-70 VII will not work. I'll try the fix. Thanks
