CryoSPARC periodically releases new patches, which you can view on the [CryoSPARC Updates page](https://cryosparc.com/updates).

### 1. Ensure your CryoSPARC instance is running
If it is not running, start it with:

```bash
cryosparc-merlin cryosparcm start
```

!!! info "The -d / --cryosparc-path option"
    If the CryoSPARC installation is not located in the default directory `/data/user/$USER/cryosparc`, specify the installation path using the `-d` option.

### 2. Download the patches

```bash
cryosparc-merlin cryosparcm patch --download
```

### 3. Install the master node patch

```bash
cryosparc-merlin cryosparcm patch --install
```

### 4. Install the worker node patch

```bash
CRYOSPARC_PATH=/data/user/$USER/cryosparc

mv $CRYOSPARC_PATH/cryosparc_master/cryosparc_worker_patch.tar.gz \
$CRYOSPARC_PATH/cryosparc_worker
```

```bash
cryosparc-merlin cryosparcw patch
```

!!! warning "Worker Architecture"
    Make sure you access the correct worker installation. For installations with **version 5** or above, the path to the worker installation has the architecture in the directory path.

    ```bash
    /data/user/$USER/cryosparc/cryosparc_worker_x86_64
    ```
    or

    ```bash
    /data/user/$USER/cryosparc/cryosparc_worker_aarch64
    ```

### 5.  Restart CryoSPARC to finalize the update

```bash
cryosparc-merlin cryosparcm restart
```
