from http://unattended.msfn.org/intermediate/ap...stallshield.htm Just wondering if you followed this step: 3. After installation has completed, go to your C:\Windows\ (or C:\WINNT\) directory and take out the setup.iss file. Put this setup.iss file in the same directory where your application setup.exe file resides in. Also, you could use Putty (http://www.chiark.greenend.org.uk/~sgtatham/putty/) that doesn't need to be installed. It can be run from anywhere.
