# Change Hexagon tool Install Path

The `HEXAGON_ROOT` environment variable tells the build system where the
Hexagon tools are installed. By default, `qsc-cli` installs the tools under
`$HOME`, but you can install them to any directory using the `--path` option.

After installation, set `HEXAGON_ROOT` to the same directory you passed to
`--path`. Use an absolute path in both commands, as shown in the following
example:

```bash theme={null}
mkdir -p <tools-dir>
qsc-cli tool extract --name hexagon8.4 --required-version 8.4.07 --path <tools-dir>/8.4.07
export HEXAGON_ROOT="<tools-dir>"
```
