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.
worked!
