hello all !
i'm currently creating a sotware DVD to silent install everything on my computer (in case of disk failure,...).

I have silentlty installed WLM2011 without problem but i can't find the parameter for Plus!

the application version is MsgPlus-502

I have tested the following parameters in DOS command line without success (always a normal installation is launching) :

/quiet
/Q
/silent
/S
/silentinstall
/silentinstallnosponsor

Could you help me please and give me the good parameter ?
If the topic already exists, could you give me the link please because I haven't found it.

thanks a lot for your help and your answer !

ok, thanks a lot !

I have tested the solution posted on this topic.

I have taken the normal install package but it's not working (and it seems that I already had the good package).

I have used   packageNAME /Silent
and I get always a window to continue by a manual installation and no silent install.

My OS is Windows 7 in 64 bit.

I have read that we can find another installer package on the system after the manual installation but i don't know the name of this installer and it's location.

Maybe I have to use this package to install silently the program (It's the process to install silently Adobe Reader for example)

I hope somebody could help me ^^

Please, always try to search the forums before making a new thread to avoid duplicated threads. As for this issue, several threads already exist which explain all in detail.

As stated in that linked post provided by Spunky, it only works on the offline/full installer (which is more than 7MB big).
With the exception that a "Thank you"-webpage will always be opened at the end of the setup.

It will not work on the online/web installer (which is less than 500KB big).
