Cypress not installing using local zip on windows

Current behavior:

When running the following command

set CYPRESS_INSTALL_BINARY=C:/temp/cypress.zip && npm install cypress@3.3.1

Where C:/temp/cypress.zip is a fresh download of 3.3.1.

The installation gets aborted because it seems like it tries to use the path as a relative external url.

> node index.js --exec install

‼ Warning: Forcing a binary version different than the default.

  The CLI expected to install version: 3.3.1

  Instead we will install version: C:/temp/cypress.zip

  These versions may not work properly together.

The Cypress App could not be downloaded.

Please check network connectivity and try again:

----------

URL: https://download.cypress.io/desktop/C:/temp/cypress.zip?platform=win32&arch=x64
Error: self signed certificate in certificate chain

----------

Platform: win32 (10.0.16299)
Cypress Version: 3.3.1

Note the URL.

I’ve tried all kinds of ways of providing the url

• Single Windows slashes \
• Double Windows slashes \\
• Normal slashes /
• File path file://C:/temp/cypress.zip
• HTTP path http://C:/temp/cypress.zip (it doesn’t make sense, but I got desperate)

It fails on the self-signed certificate because of the corporate proxy.

Desired behavior:

Able to install from a local zip as described here https://docs.cypress.io/guides/getting-started/installing-cypress.html#Install-binary

Steps to reproduce: (app code and test code)

• (Uninstall Cypress)
• Download Cypress from any mirror
• Follow the instructions in the Cypress docs using the path to the file you downloaded in the previous step as the install binary.
