Weird install problems are often due to virus or anti-malware software that doesn't play well with the installer. Is your PC running protection other than the standard Win 10 stuff? If so try temporarily disabling it.
You may have to manually delete files, probably Canon support can help you through that process but definitely create a system restore point before you start deleting files and/or editing the registry so you can recover if something bad happens.
I recently upgraded my desktop (HP Z820 running Win 10) to 4.7.2 after I upgraded to a newer camera and the install went quickly with no issues. Mine has the Fall "creators" update installed so Windows is current on it like your machine although this is the 64 bit pro instead of home edition so that MIGHT make a difference but I doubt it.
My only concern/complaint with DPP 4.7.2 is the noise reduction processing seems a bit slow. My desktop is running dual 8 core processors with 128 GB of memory. DPP is currently running on its own 2 TB drive. I am considering upgrading my GTX-570 graphics card to something faster to see if that takes care of the lag since NR can take up to 10 seconds to finish; any other adjustments are instanteous as they are applied and I note that NR is also much slower after digital lens correction is also applied. Interestingly during the time NR is doing its thing CPU core utilization spikes for maybe 1/4 second to nearly 50% before dropping into the 15-20% range while processing finishes and memory and drive controller utilization stay in the under 10% range the entire time so there are plenty of resources available to DPP.

I am planning on switching to a Nvidia GTX 1080 when the run on graphics cards due to the crypto currency "mining" craze falls off. Right now the price on the medium to high end graphics cards is nuts due to this latest get rich scheme to infect society. Nvidia has an "alert me" button on their webiste and I signed up for notifications and will keep an eye on the internet sites to see when supply starts catching up with demand.
That card is probably a little overkill but buying at the upper performance end usually means it will have a longer usable life as new and more resource hungry programs appear.
