Icons for Different Install Types

I have been hunting the forum and archives for an answer (which I'm sure will be simple).

I have customers who cannot comprehend that there can be more than one type of install (the drop-down box is just too much for them).

Is there a way I can have a screen with two icons or two buttons that force the user to choose the install type?

Just for clarification, I am not using the MUI, just the default one.

you can do this using InstallOptions. you can place radiobuttons and bitmaps for each installtype. check the docs (NSIS\Contrib\InstallOptions) and the examples (NSIS\Examples\Modern UI).
