Open in TheBrain

Update #99247

https://thebrain.zendesk.com/agent/tickets/99247

Hello Stephen,

Thank you for confirming the installer version. That helps clarify what’s going on.

The build you’re currently running (15.0.95.0) is an older early v15 build. The error you’re seeing about the menu failing to render is consistent with a UI initialization issue that has been addressed in later v15 updates.

The best next step is to update to the latest available TheBrain 15 build, which includes fixes related to menu rendering and startup issues.

Please do the following:

  1. Fully close TheBrain if it is running
  2. Download the latest TheBrain 15 installer directly from our website:
  3. https://www.thebrain.com/download
  4. Install over your existing copy (no need to uninstall first)
  5. Launch TheBrain and confirm the version under Help > About

Once you are on a newer build (15.0.99 or later), please check again under:

Main Menu > Settings > AI > Local AI

That is where the Local AI endpoint configuration is available in TheBrain 15.

If TheBrain still fails to open after updating, please send a fresh Output.log captured immediately after the failed launch. You can find it here:

Win + R, then paste

%LOCALAPPDATA%\TheBrain\Logs

Thank you for your patience, and for working through this with us. You were right to question the missing UI, and the version difference turns out to be the key factor here.

Best regards,

John
