Nice for a site licenced app!!
Thank you for contacting the LEGO Education Technical Support line.
Your customer number is XXXXXXXXXX
Unfortunately we are not able to support installation of the software across a network due to many variables involved in this. We therefore recommend standalone installation only.
However, on the software disc, located in the folder called 'bin', there is a file called 'silent_install.txt', which may be of help.
Alternatively you may wish to visit one of the Internet forums.
Instructions on how to do a silent install can be found in the file 'silent_install.txt', which is located in the folder 'Bin' on the LEGO Mindstorms NXT education CD.
For further information or support please contact your distributor
