Details

Joomla! Extensions can be installed using one of three methods, as indicated below. Only one method is needed to install a given Extension.

The normal procedure for installing a Joomla! Extension is as follows:

  1. Download one or more archive files (normally ".zip" or "tar.gz" format) from the Extension provider's web site to a local directory on your computer. Note that some Extensions are installed as one file (for example, one Component or Module) while other Extensions might have two or more files (for example, a Component and a Module). If there are two or more parts, each one will have its own archive file.
  2. Choose one of the methods describe below (usually Package File)
  3. When it is finished, the screen will display the message "Install Component Success". If the installation is not successful, an error message will display.
  4. Depending on the Extension, it may be necessary to enable the Extension (for example, in the Module Manager or Plugin Manager).


  1. Browse to the location where you downloaded the Extension's archive file.
  2. Then press "Upload File & Install". Joomla! will read the contents of the archive file and install the Extension.
