Sorry for not providing an update.
I tried garlin's method and it didn't work.
For one thing, the /silent parameter was incorrect, it was /Q, but even so the program still asked me to extract the files.
I guess I should have communicated what I wanted to do, and I apologise that I didn't do such a thing. I want NTLite to perform a silent installation of DirectX 9.0c. Again, sorry.
Now, would the updates section help with such an endeavour?
