Use command line to run Dameware Mini Remote Control

We have been using cmd to run dameware for a long time, but with some picky computers we want to try also specifying the -d: parameter, however it caused it to break. What is right syntax to use?

For demo purposes, our domain is DEMO.COM.

Command: start "DameWare" "C:\Program Files\DameWare Development\DameWare Mini Remote Control\DWRCC.exe" -c: -h: -d:DEMO -m:%1 -a:1 -v:

This results in a 'error' and a reminder of what syntax to use, but I am not seeing a specific example of a completed command including the d: parameter. Help?
