DTLite Command Line Not Working

Hi,

Could anyone help me with what is wrong here.

I installed DTLite 10 on Windows 2008 but the command line does not work as expected. Every command just launches the GUI

For example:

DTLite.exe -get_count
DTLite.exe -mount, F, "C:\Test.vhd"
DTLite.exe -help

all of the above and any other always result in the same thing, which is launch DTLite window.

I have also tried these on my Windows 8 PC and it is the same thing.
