I have couple of user defined variables whose values are not read from the installer.properties when I run the silent installer.
GUI works fine and response file also is generated with correct values for the user defined variables.

However, when I try to run the silent installer as
setup.exe -i silent -f installer.properties

the values for these variables are not read and are set to null/empty.
Rest everything works as it should in the sequence and installation also does not report failures. but since the values for the variables are not set, the output is not desired one.

Can someone help me determine what could be the problem here and how to resolve it?
