NSIS Select Pop-Up Dialog

The NSIS Select plugin provides a simple modal pop-up dialog from which the user may select from a list of items. It’s far simpler to use than the nsDialog plugin and doesn’t require creating an entire custom installer page when all you need is a simple combo box.

Requirements

The UNICODE plugin requires at least NSIS 3.0. The ASCII plugin should work with NSIS 2.xx. I haven’t tested (much) at all with NSIS 2.xx, so if there are issues using the plugin with that version, let me know.
