How to Choose install destination folder with a silent install?

[brotherik]

hello!!!

First sorry for my english.

for me is important install the software in other folder diferent to Program Files.

On my computer I usually structure my folders like this :

C:\PROGRAMS\Video\

C:\PROGRAMS\office\

...etc.

I have done Unattended disc windows + programs and I use the method RunOnceEx from cd for instal the application but I would like choosing the destination folder for my apps.

With vlc and spybot no problem because the installers are made with inno setup and NSIS. For example i use:

/DIR=%systemdrive%\PROGRAMAS\MANTENIMIENTO\CAZAESPÖAS\SPYBOT /GROUP=MANTENIMIENTO/CAZAESPÖAS/SPYBOT" /f

But I don´t Know with firefox,nero,winrar...etc.

What can i do?

I’m hopeful that it will be easy because I´m noob.

So if someone could be kind enough to answer me, be sure I would really appreciate any help.

thanks!!
