Although the cache viewer can be directly opened via the control panel, it must be done using the command prompt opened via Run As Administrator to set the correct permissions.
From the Java Cache Viewer you will select the Orchestration Installation application object or the Agent Installation depending on which you are installing. With the appropriate choice selected, click on the green play button at the top of the cache viewer box and the installation will proceed as expected.
