Go to Canon and select your camera model under software downloads. At the time this guide was written, the link was https://www.canon-europe.com/support/consumer_products/software/eos-utility.html
Select your camera and download "EOS Utility 2.14.20a Updater for Windows" (yes, we will do full install with this file).
Before we can run the installer we need to add a key to our registry.
Open a commandprompt as admin and run this to create the right key for a full install.
REG ADD "HKLM\SOFTWARE\WOW6432Node\Canon\EOS Utility"
Now you can run "EOS Utility 2.14.20a Updater for Windows" to make a full installation.
To get it to work on my win11 system,
uninstall the EOS app ( if installed) and reboot.
Using regedit I entered the new key BY HAND,
{ if you have never used regedit there are "youtubes" on it.}
If you can edit a text file. you can change the registry. worst case is EOS does not work but you are there anyway.
I then ran the update and , yeah, it worked.
Doing it by hand should overcome any PATH issues.
Sorry for being so abrupt,
