The blank window that is not the ZIP

A missing MSVC runtime looks exactly like a corrupt download. The overlay never appears, and people hit redownload five times.

Install the latest supported x64 Visual C++ Redistributable from Microsoft, reboot if Windows asks, then run Kiddions elevated. Do not install random “all-in-one runtime packs” from ad pages.

If the runtime is present and the overlay still dies instantly, check SmartScreen quarantine on safety and architecture on requirements.
