Apparently Canon has decided to make the complete Software disk 28.1A containing DPP, EOS Utility, and Picture Style Editor is available for download. The rest of the Canon software will have to be downloaded individually..
A Serial number is required, my 5D MK III serial number worked fine.
Great news for those with lost disks or installation issues. Many laptops do not have CD Rom drives, so this is a solution.
I wonder why it took them so long to realize this? At least, they finally did.
