53* **On Windows, an update said "restart aborted" or "The update is installed"**: don't quit Claude Science or run `claude-science stop`, and don't shut down or restart your PC, or sign out of Windows. Letting your PC sleep doesn't close Claude Science. If security software is blocking the new version, Claude Science might not open again. Select **Update now** or **Restart to update** again after a few minutes. If it still fails, ask your IT team whether security software is blocking Claude Science, and send them [Where the app stores data](/docs/claude-science/manage-on-devices.md#where-the-app-stores-data). If you don't have an IT team, contact [Claude support](https://support.claude.com/en/articles/9015913-how-to-get-support).

5454* **Claude Science still asks you to update**: on Windows, if an update said "restart aborted" or "The update is installed", follow the entry above instead. On a Mac where Claude Science opens in its own window, quit it with Command-Q, wait ten seconds, then open it from your **Applications** folder. Anywhere else, run `claude-science stop` in a terminal (on a Mac or Linux, if the command isn't found, type `~/.local/bin/claude-science stop`), quit Claude Science if you're on a Mac, then open it again. If `claude-science stop` says "Not killing pid", follow [the terminal steps](#from-a-terminal-or-on-a-server).
55* **The message says "restart aborted" or "The update is installed"**: on a Mac or Linux, if you started Claude Science from a terminal, follow [the terminal steps](#from-a-terminal-or-on-a-server). Otherwise, follow [restart aborted](/docs/claude-science/troubleshooting.md#restart-aborted).
55* **The message says "restart aborted" or "The update is installed"**: on a Mac or Linux, if you started Claude Science from a terminal, follow [the terminal steps](#from-a-terminal-or-on-a-server). Otherwise, follow [restart aborted](https://claude.com/docs/claude-science/troubleshooting.md#restart-aborted).
5656* **The message says "the new version couldn't start"**: you're still on the version you had. Updating again, even from a terminal, gets the same version until a newer one is released, so contact [Claude support](https://support.claude.com/en/articles/9015913-how-to-get-support) with the exact words you see.
5757* **Anything else**: on a Mac where Claude Science opens in its own window, contact [Claude support](https://support.claude.com/en/articles/9015913-how-to-get-support) with your version and the exact words you see. Anywhere else, [install Claude Science again](#install-claude-science-again), and contact support if that doesn't work.
