Software Deployment

Hi,  I am trying to silently install Silverlake teller capture.  the creator has included an xml answer sample file that is commented however it does not have any area for the install path which is a question on the verbose setup and it does need to be set.  so for example on the select your scanner model screen on the verbose setup you would have a model ts-240 in the drop down list.  in the xml answer file a ts-240 model is = to "9" and thus you put in <scannertype>9<scannertype> but there is nothing for install path.  so my  question is is there a way to capture for example on the verbos install where I selected ts-240  and translate that in to <scannertype>9<scannertype>  what I need to capture is on verbos - installation path and translate that into something like <path>c:\programfiles<path>   but since its not commented for that in the xml file I was hoping there was a way to capture what it really needs to be (assuming that it can be done).  I already tired <path> and <installpath> and a few others.   I have never heard of anything that could do this but I'm asking and hoping there is.  or even better,  someone from Jack Henry and Associates on this web site that would answer this.  a support call to them resulted in not willing to help with scripted silent installs.  they want us to manually install a couple hundred workstations across a few states.
