# Installation or update

Download the latest version of the zimlet package from [https://www.intalio.pl/en/zi-licensesystem-downloads](https://www.intalio.pl/en/zi-licensesystem-downloads) and unpack it in /tmp (as root):

```
cd /tmp
wget https://www.intalio.pl/sites/default/files/modules-files/zi-licensesystem-1.0.15-zimbra9.tar_.gz
tar xvzf ./zi-licensesystem-1.0.15-zimbra9.tar_.gz
```

Run installation script (as root):

```
cd ./ZI-LicenseSystem-1.0.15-Zimbra9/
perl ./ZI-Installer --install-deps
```

At the beginning required perl packages will be installed if they are not available in the system already:

In the last step you will be asked to restart mailbox service. **You can skip it (answer: N) and restart mailbox service manually later but until that zimlet will not work properly.**

<p class="callout info">If you are going to install another zimlet right after this one it's not necessary to restart mailbox at this point and you can do it only once after installing the last one.</p>
