# Homebrew: Error: It seems there is already an App at '/Applications/Chrome.app'

**Code:** `Homebrew Cask: It seems there is already an App at` · **Category:** macOS · **Seen on:** macOS

A cask install failed because the app is already installed manually (or a leftover exists).

## Meaning

Adopt the existing app into Homebrew with `brew install --cask --adopt NAME`, or remove the old app, or use `--force` to overwrite. Don't mix manual and cask installs of the same app without adopting.

## Common causes

- App installed outside Homebrew
- Leftover app bundle after a failed uninstall
- Different app with the same name
- Quarantine/permissions blocking removal
- Cask renamed

## Quick fix

1. `brew install --cask --adopt NAME`
2. Remove the old app and reinstall
3. `brew install --cask --force NAME`

## Detailed fix by platform

### macOS

1. `brew list --cask | grep -i NAME && ls -ld /Applications/NAME.app`

## How to diagnose

1. **Installed** — Manually or via cask?
2. **Option** — Adopt or force?
3. **Leftover** — Old bundle?
