- Go to the back end, in other words – login as the administrator.
- Select Extensions – Extension Manager and go to 'Upload Package File'.
- Click Browse, locate the installation package of the component you want to install from your workstation where you have downloaded it earlier and click 'Upload & Install'.
Always check that the extension is compatible with your Joomla version before installing it. Don't expect 1.5 Extensions to work in Joomla 1.6.
