The following syntax is used to install MSDE using all of the default installation settings:
MSDEx86.exe -s -a -f1 "<path>unattend.iss"
MSDEalpha.exe -s -a -f1 "<path>unattend.iss"
<path> should represent the full path to the unattend.iss file. You must always indicate the fully qualified path to the .iss file. See below for sample iss file.
To use installation settings other than the defaults, a copy of the unattend.iss file can be edited and passed on the command line. For example, assuming that a copy of unattend.iss is copied to c:\temp, renamed to "mydefaults.iss" and edited. It would be possible to install MSDE using this new .iss file by issuing the following command:
