Beginning with version 3.0.1 we allow for the location of the VUE home folder to be configured by an environment variable, we also allow for specifying a location for the installed data resources which can be searched within VUE.
1) VUE Home Folder
Set an environment variable called VUEUSERHOME to point to a new home folder.
2) Data Content Folder
Set an environment variable called OSIDPROVIDERHOME to point to a new folder.
If you're on Mac OSX you'll need to set the variables in the Info.plist, if you're on Windows they can be set through the control panel.
