YMMV of course, but I discovered that the installation failure of V1.2 (also 1.0, 1.1) on Windows 10 Home (64 bit) was failing because of some extra (and very, very good, I might add) security software called RegRun. (This is a homebrew PC but the issue was not the home-brewing.)
TL;DR Disable the RunGuard/Registry Guard
Details: Windows event log showed this in the Windows Logs... Application, source Application Error.
Faulting application name: Setup.exe_EOS Webcam Utility, version: 1.2.2.0, time stamp: 0x61000c76
Faulting module name: RRShell.dll, version: 1.0.1.2, time stamp: 0x49d9b75a
Exception code: 0xc0000409
Fault offset: 0x00009b36
Faulting process ID: 0x5a5c
Faulting application start time: 0x01da1eba2509091b
Faulting application path: D:\Downloads\Canon\EOSWebcamUtility-WIN1.2\Setup.exe
Faulting module path: C:\PROGRA~2\Greatis\REGRUN~1\RRShell.dll
Report ID: c776ae98-c554-46a4-a82b-5236b2de3d08
Faulting package full name:
Resolved by running RegRun Control Centre and doing this:
"Enable RunGuard" unchecked; "Enable Registry Guard" unchecked. RunGuard Settings... unchecked "RunGuard is active"
Installation then ran "normally" and looks OK (target folder created, EWC service installed, IIRC)
Hope that helps someone.

Just to clarify WADDIZZLE, I was responding to this comment you made: "All the members reporting the issue are running on DIY platforms. It is a fact they do not wish to discuss."
Thus your response of "I take exception with your broad stroke generalization that I was speaking about all members experiencing issues with the EOS Webcam Utility."
It's two sides of the coin. I did not imply you were commenting about "all members" that have any issue but rather your comment that "All the members reporting the issue..." have a DIY machine.
As for the comment about nothing for Cannon to fix I am not sure that is accurate. I had asked what service are being looked at when it installs. No response. Now it's only on one W11 machine the EWCService fails to install/run. It does install..it is just the the error that others have gotten about unable to start the service. And that is not a home brew, it came with W11 preinstalled.
The other machines (W10 and W11) it installs, but will not open the actual Cannon utility. The drivers load and the camera connects but, for example, in OBS and other software, it only shows the "logo" screen. Only one of those is a "home brew."
As for asking ms about it a search will return a few hits, The one the relates to the issue about the app not opening the reply is: "It is likely that there's something wrong with the driver for your Canon camera. So, consider downloading a proper driver from Canon and installing it. As for which driver you need, you'll have to contact Canon. ~ Yuhao Li Microsoft Community Support Specialist".
