HI All I'm having a good headache trying to silently install Vectorworks 11 and Sketchup 4. Respectively, they use Wise and Installshield installers. I have tried with the switches on the Wise knowledge base, tried with the .iss installation procedure and more but all to no avail. Does anyone know how to do a silent install for these two programs? or lead me to some more info to achieve it? Many thanks.
