This articles explains pre-installing the Elo touch driver on Windows XP fails

Driver packages (6.9.24 or newer) do not support pre-install nor silent install on Windows XP.
During standard installation, users need to manually click away all Microsoft driver digital security warnings to proceed and complete the installation. 

Each time a new device is connected, the driver has to be installed again.
It's possible to install the package silently on Windows XP if the system's driver signing is disabled:
Windows Control Panel - System - Hardware - Driver Signing - Ignore.
