If you install Alfresco using the setup wizard, AOS is installed as a component at the same time.
A fully-compatible SharePoint repository is also installed, that allows Microsoft Office Suite applications (for example, Word, PowerPoint, and Excel) to interact with Alfresco as if it was SharePoint. This feature allows you to edit Office documents in Alfresco Share and to modify Office files without checking them in and out. Alfresco locks the file while it is being modified and releases the lock when the file is saved and closed.
If you are installing using the setup wizard, choose the installation wizard that you
require (for your platform) and follow the instructions in Installing Alfresco using setup wizards.
If you use the Easy install option, Alfresco Office Services is installed by default. If you use the Advanced option, ensure that in the Select Components window, you check the Alfresco Office Services box.
If you are installing the Alfresco repository manually, or are installing into an
existing Alfresco instance, install the AMP file, alfresco-aos-module-1.1.7.amp, which deploys the
See Installing an AMP for information about installing an AMP file.
