You create a script by using a text editor such as Notepad and then saving it in ASCII format in a file with the file extension .vbs. The script consists of one or more commands, as well as command switches that specify options, and flags that modify the options. An installation script also contains path names.
An installation script points to the location of the product's setup.exe file. You must point to the setup.exe file on your product CD. For example:
AutoCAD 2008 CDROM1\setup.exe
