Magento Connect Manager

Access the Magento Connect Manager through System → Magento Connect → Magento Connect Manager in the top menu.

If you see an error similar to the one being displayed below, you will have to adjust the permissions for the Magento directory before you can continue. If you are not sure how to do this, we advise you to contact your web administrator and ask him or her to make your Magento directory and all of its subdirectories writable. You can also refer to this page on the Magento Community: http://www.magentocommerce.com/wiki/groups/227/magento_connect.

Log in using the same username and password you used to access your Magento administration panel. If you are not allowed access to the Magento Connect Manager, it may be because your user does not have permission to enter it, in which case we advise you to contact your Magento administrator and ask him or her to help you.

Click on the Settings tab and make sure that the dropdown box Preferred State has the option Stable selected.

Click on the Extensions tab and enter the following text:magento-community/MageParts_CEM In the field preceded by the text Paste extension key to install, and click the button.

Click the Return to Admin link once the installation has completed to return to the administration panel, or click the Log Out link to log out.
