Error #3501 – "License Required" on Personal Gmail Account (Not Enterprise) – Request for Backend Account Routing / Entitlement Check

Hi Antigravity Team,

I am a personal user with a personal Gmail account, not a Google Workspace or enterprise user. I am unable to use Antigravity because of error #3501. The application shows the following message:

“You do not have a valid license of this product. Please contact your administrator to request a license. If you are not an enterprise user and believe you are receiving this message as an error, please try using the latest version and logging in again. (#3501)”

In the settings, it also says: “License Required”.

I do not have an administrator to contact because this is a personal account. I have already tried all the usual local troubleshooting steps, but the error persists.

Environment:

  • Antigravity version: 2.14.0
  • Operating system: Windows 10
  • Account type: Personal Gmail
  • Country/Region: United States

Troubleshooting steps I have already tried:

  1. Updated Antigravity to the latest version.
  2. Signed out and signed back in, making sure to select the personal account, not a business or enterprise account.
  3. Cleared caches and deleted the local configuration folders, including:
    • %APPDATA%\Antigravity
    • %LOCALAPPDATA%\Antigravity

Despite all of these steps, the same error #3501 and “License Required” message still appear. Since this is a personal Gmail account, I suspect the account may be incorrectly routed to enterprise license validation on the backend, or an internal entitlement flag such as “antigravity_entitled” may not be set correctly.

Could you please:

  • Check the account routing for my account on the backend.
  • Verify and manually reset any internal license or entitlement flags if needed.
  • Re-sync my account on the backend.
  • Confirm whether a region restriction could be causing this misleading license error.
  • Provide a workaround if one is available.

I can provide my account email privately if needed. Thank you for your help.

Best regards,
