# Installation and startup problems

Verify the installed package, runtime, and service status before reinstalling Foxora or removing any local data.

[![Installation and startup problems](/docs/images/v5.0.8/reference/settings-advanced.webp)](/docs/images/v5.0.8/reference/settings-advanced.webp)Studio interface in English. Sample data.




- For Desktop, use the current download from [foxora.ai/download](/download); for CLI, verify `foxora --version`.

- Restart the app or terminal after installation and complete operating-system security prompts.

- In Desktop, open **Settings → System** and recheck the runtime and service tiles.

- In CLI, run `foxora setup`, then `foxora doctor`.

- Record the first failing check before repeating installation.




Do not delete `~/.foxora` or `%USERPROFILE%\.foxora` during diagnosis. That directory can contain sessions, memory, settings, and authentication state; export important data first.




**Expected result:** Studio opens or `foxora doctor` identifies one failed installation, runtime, authentication, or network layer.
