You can tell which was done by looking at the "Goodies>One-Click Installs" page on the web panel. If the domain shows up under "Modify / remove previously installed software (easy)?", then it was an "Easy" install. If it shows up under "Upgrade or remove previously installed software (advanced)?", then it was an "Advanced" install.
