Silent install for SRI and SRC

After being frustrated by Scholastic tech support and being told there is no way to make the installer for Scholastic Reading Counts Enterprise or Scholastic Reading Inventory Enterprise install silently, I was determined to find a way. Here are the results of my exercise:

Step 1:
Find the \SRI_Client\Windows (for Reading Inventory) or the \SRC_Client\Windows (for Reading Counts) install folder.

Step 2:
Create a file named installer.properties

Step 3:
Edit installer.properties in a text editor such as notepad or wordpad and insert the following text
INSTALLER_UI=silent
SERVER_IP=your_sri_servername_or_ip_here

Step 4:
Save the file

Step 5:
Deploy using the software deployment tool of your choice. We happen to use Systems Center Configuration Manager, the successor to SMS from Microsoft.
