Introduction

DuckDB is a high-performance, columnar in-memory database that provides a SQL interface to data stored in memory. It is designed to be fast, flexible, and easy to use. However, some users have reported issues with the UI extension on Windows ARM. In this article, we will explore the issue and provide a solution.

What happens?

When trying to run the UI extension on Windows ARM, users receive a message stating that the UI extension is not a valid Win32 application. This error occurs because the UI extension is compiled for x86-64 architecture, which is not compatible with Windows ARM.

To Reproduce

To reproduce the issue, follow these steps:

Download the ARM version of DuckDB: Go to the DuckDB website and download the ARM version of the database. You can find the download link on the DuckDB documentation page.
Run the UI extension: Once you have downloaded the ARM version of DuckDB, run the UI extension by typing duckdb -ui in the command prompt.
Observe the error message: You will receive an error message stating that the UI extension is not a valid Win32 application.
