Note:
When you precache the local installation source, Setup copies the Updates folder from the network installation point to the local installation source. In this manner, your customizations can be included in offline installation scenarios. This is the only circumstance in which Setup caches the customization file on the local computer before the installation.
For more information, see Precache the local installation source for Office 2010. The information also applies to Office 2013 Preview.
Apply software updates
At the end of the installation process, Setup checks the Updates folder on the installation point for software updates (.msp files). Unlike Setup customization files that you create by using the Office Customization Tool, software updates are distributed by Microsoft to enhance the product.
If you are deploying Office to users and you also have to deploy a set of software updates, Setup can apply the updates as part of the initial installation process. Costing (estimated required disk space) and progress bar indicators all take this step of the installation process into consideration. From a user's perspective, the complete process is a single event. This model preserves the original installation point and still lets you give new users the most
Note:
The Updates folder is used only for initial or new installations of Office 2013 Preview. The Updates folder can contain only one Setup customization .msp flle, and multiple service packs and hotfixes that are in .msp format only.
For more information about the software update process, see Consolidated update process.
Including more than one product on the installation point
If the network installation point contains more than one Office 2013 Preview product, Setup searches all folders and subfolders for Config.xml and Setup.xml files and then prompts the user to select a product to install.
If you are installing more than one Office product, it is more efficient to store all the products on the same installation point and then customize Setup to install a specific Office product on users' computers.
Note:
When you copy multiple Office products to the same installation point, you might be prompted to overwrite shared Setup files. Because these files are duplicated among all Office 2013 Preview products, you do not have to recopy any of the duplicate folders. When you are prompted to overwrite duplicate Setup files, choose No. This efficient design saves space and ensures consistency when you create and replicate network installation points.
