Somebody know which switcs to use ?
I tried this but still asking for install
start /wait %systemdrive%\Install\Applications\PhotoFiltre\PhotoFiltre.exe /S

Use WINRAR

Setup=pf-setup-en.exe /S
TempMode
Silent=1
Overwrite=1

Nice program. I have adopted to using it.
Definately the correct uppercase switch that a Nullsoft Installer uses. I would expect that to work unless you have an incorrect path or filename.

that switch doesnt seem to work for it but seeing as the installer doesnt require any registry entries being added u can simply make it in WinRAR.

heres a silent sfx winrar installer.

Download Here

Are you sure? I just double checked silent installing PhotoFiltre v6.1.5 and I find that the /S switch works fine. You are using an uppercase S?

oops i used small S, oh well my winrar one works just the same.

I am sure because i just do a fresh unattended install.
PhotoFiltre v6.1.5 starts to install but not silent, still in manual install.

just use the winrar one i posted if its not working as its the same anyway. no need for any switches

I have used /S for awhile now...

The picture you show is an english installer and since only one download link is available for it, then you should have exactly the same installer as mine. An Uppercase /S works. If you still have doubts, then you can upload it to a host and I will download and test the installer for you. Just pm me a link if you do so.
I would rather fresh install it with /S rather then the trouble of installing a new version and repacking the files with WinRAR each time a new version is released (even though ScubaSteve is nice enough to share his archive).

Thanks for the help, i will trie ScubaSteve's installer soon as possible
