XML : Does the Click-to-Run configuration.xml need "SourcePath" added to it?

I am trying to install O365 on a sandbox server for our office hosted in Amazon S3.

Normally we run this on local machines and point the SourcePath to the fileserver and to the Apps folder.

This server can't reach the file server because it's hosted in very restricted environment. Can I remove the SourcePath from the XML file and replace it with something else, or can I point it back on itself to make this work?

Below is the current configuration we are using to install the Office 365 software.

  <Configuration>   <Add SourcePath="\\FILESERVER\Apps$" OfficeClientEdition="64">      <Product ID="O365ProPlusRetail" >        <Language ID="en-us" />      </Product>   </Add>   <Display Level="None" AcceptEULA="TRUE" />   <Property Name="SharedComputerLicensing" Value="1" />   <Logging Level="Standard" Path="%temp%" />  </Configuration>
