I have created a software suite of Labview and Multisim using this information.

Then our system admins run it through the VLM to create a VLI installer using this information.

Then when I get it back it has these 4 files.
_Src
Client
Install.exe
vli.id
Then I run start /wait install.exe --quiet --accept-eulas --prevent-reboot
But get an error stating 
One or more errors occurred while parsing command line arguments:
Unknown flag: /-quiet.
 
I also tried --passive with the same results.
 
 
I also read this

So I created an installer as followed.
 
start /wait _Src\Install.exe --quiet --accept-eulas --prevent-reboot
start /wait Client\vlmclient.exe /q
start /wait Install.exe --quiet --accept-eulas --prevent-reboot
 
 
 
Which gives the same error I mentioned earlier.
 
When I do an install.exe -h it lists the right commands and the commands I am using are correct.
 
How do I get silent install of this?
 
Very frustrating that a person has to jump through all these hoops just to get a silent installer.
