-1 and 2

[Lujain]

Hi all,
Please I want to know what is the meaning of -1 2 in the deployment package.

Because I made an simple configuration with just check and install.
for more information; I can install the program with command line in the local machine and via the server.

Other things, when we using the command line to install some programs have generate a windows box message! and i have to choose the language! how can I avoid the windows message (choose language).

therefor I try /s , /qn , /quiet , /auto, /norestart , /v, /passive
