It's not important if you use Windows 64 bits or 32 bits.
If your application is 32 bits then you need to use the 32 bits
package called
cef_binary_79.1.31+gfc9ef34+chromium-79.0.3945.117_windows32.tar.bz2
That
package only works if you installed the latest CEF4Delphi version 79.1.31 which I uploaded today.
If you installed an older CEF4Delphi component then you have to uninstall the old CEF4Delphi version and then install the new version.
