To do a silent installation af M$ Autoroute 2007 do the following (it worked for me) 1. create an adminstrative point: setup_ar.exe /a - point it to a folder. 2. when it is done locate and open data.msi with orca. under the feature section there a (in my edition) two choises. note the install value - in my case 500. 3. now install M$ Autoroute full install: msiexec.exe /i "data.msi" /qb INSTALLLEVEL=500 that did it for me
