404 error attempting pre-release binary install on Windows ARM

[MikeMcC399]

Current behavior

The win32-x64 pre-release version ec252f8601d9cec4543085667c7e03ecdab8e82f fails to install its corresponding pre-release binary on the GitHub runner windows-11-arm

The logs show:

cypress:cli URL: https://cdn.cypress.io/beta/binary/14.5.0/win32-arm64/develop-ec252f8601d9cec4543085667c7e03ecdab8e82f/cypress.zip
    Error: Failed downloading the Cypress binary.
Response code: 404
Response message: Not Found

This affects the pre-release version only, the pending release version has a different code-path.

Desired behavior

When installing a pre-release version on win32-arm64, the associated win32-x64 binary should be downloaded.

@AtofStryker

I'll submit a follow-on PR to fix this, so that the change can also be tested from a pre-release version.

[AtofStryker]

@MikeMcC399 hitting https://cdn.cypress.io/beta/binary/14.5.0/win32-arm64/develop-ec252f8601d9cec4543085667c7e03ecdab8e82f/cypress.zip in the browser or terminal works fine. I am wondering if there is an issue with the cloudflare cache. I am going to purge it and will comment when that is done

[AtofStryker]

@MikeMcC399 just purge the cloudflare cache. Can you try installing again?

[MikeMcC399]

@AtofStryker

There shouldn't be any https://cdn.cypress.io/beta/binary/14.5.0/win32-arm64/develop-ec252f8601d9cec4543085667c7e03ecdab8e82f/cypress.zip available, but strangely in a browser behind the scenes it returns a 404 and then falls back to download a win32-x64 version from a Windows machine, or linux-x64 from a Linux machine

wget fails though

The code path for pre-release is different. I already tried out a patch which works. I'll submit a PR for this tomorrow.

Thanks for your support!
