!ANSwR
ANSwR is a modeling program which functions with [ARCGIS],  it was not on the image for the 2005-2006 school year and nobody missed it, so whether or not it is necessary to install is questionable. 
----
ANSwR is stored on [beagle].  It may be prudent to add it to the [ISO Drive|?page=software_storage].
----
If ANSwR is installed after [ARCGIS], Arcgis will pop up and say it needs to set something up and run several times.
