Using the installation instructions here, I am trying unsuccessfully to install an Agent to a Windows machine to a non-default location

This command runs successfully and installs a Windows Service for the agent:
java -jar atlassian-bamboo-agent-installer-4.4.5.jar http://abc-bamboo01:8085/agentServer installntservice

However, it is creating a 'bamboo-agent-home' directory under the current user's profile. I want to relocate this directory.
Following the installation instructions I have attempted many variations but get the same error:
Error: Could not find or load main class .home=D:\Bamboo\Home

With the Jar file in the D:\Bamboo directory, I have tried:
java -Dbamboo.home=D:\\Bamboo\\Home
-jar atlassian-bamboo-agent-installer-4.4.5.jar...etc
java -Dbamboo.home=D:\Bamboo\Home\ -jar atlassian-bamboo-agent-installer-4.4.5.jar...etc
java -Dbamboo.home=Home -jar atlassian-bamboo-agent-installer-4.4.5.jar...etc
java -Dbamboo.home=D:/Bamboo/Home/ -jar atlassian-bamboo-agent-installer-4.4.5.jar...etc

Have also tried the above with "-Dbamboo-home", but without success.

The above commands were executed on Windows Server 2008 Standard, using Powershell, running as administrator.
