Google-chrome – How does Google Chrome installer work


I have been wondering – how does Google Chrome install in a single click?
Its not ClickOnce (that behaves differently) and this works cross browser. Any ideas?

Best Answer

It actually is ClickOnce.

 function installViaClickOnce(opt_navDocument) {
    queueThankyou(10000, '\x26clickonceinstalled=', opt_navDocument);
    downloadInstaller(areStatsEnabled(), _GU_buildClickOncePath, "/update2/installers/clickonce/GoogleInstaller_en.application");

Google's ClickOnce application installs the installer for Chrome which in turn does the download for the browser.
