What Windows version are you using?
You may need to upgrade to a newer operating system to run the latest CEF version. This is a quote from the information page :

There are only two demos compatible with Delphi 7 : SimpleBrowser and SimpleBrowser2Google announced that they would drop Windows XP support for Chrome in 2015. The last CEF3 branch that was compatible with Windows XP was 2623, released in 2016.
Since CEF4Delphi uses the latest CEF3 branch, it's not compatible with Windows XP, Windows Vista, Windows Server 2003 and Windows Server 2008.
CEF4Delphi needs Windows 7, 8, 8.1, 10 or newer to make it work but if you need to test some other Windows version just download and try to run the CEF3 Sample Application from the CEF3's downloads page.
If you need to test other demos download Delphi 10.2 Starter from embarcadero. It's free !
