Hello Google Antigravity team,

We are evaluating Google Antigravity 2.0 on enterprise-managed Windows PCs.

The installer was downloaded from the official Google Antigravity website.

Environment:

  • Product: Google Antigravity 2.0

  • OS: Windows 11 Pro 25H2

  • Installer: Standard installer from the official website

  • Account: Google Workspace Enterprise Standard

  • Google Workspace AI Ultra Access: Not subscribed

  • Scope: The same issue occurs on multiple internal PCs

Issue:

When we run the installer, nothing appears on the screen.

The installer process appears in the background processes for a few seconds, then exits. No setup window, error dialog, or Google sign-in screen appears.

Since this happens before Google sign-in, we would like to clarify whether this is an installer issue rather than an account or license issue.

Could you please confirm:

  1. Does the installer require Google Workspace AI Ultra Access or any Google account license just to launch?

  2. Is Windows 11 Pro 25H2 supported by Google Antigravity 2.0?

  3. Where can we find installer logs or diagnostic information on Windows?

We have already contacted Google Workspace Support, but their response mainly covered Workspace account access and AI Ultra Access. We would like to investigate the installer behavior separately.

Thank you.
