Installer only installs one item out of twenty!

[cirerita]

Hi there,

I'm a 100% newbie, and I'm using HM NIS editor's wizard to create my setup file. I'd like my setup file to install some filters and codecs for HTPC use. However, no matter how many items I list in the wizard's window, I only get the first one to work. That is, the first filter -let's say "aacparser.exe"- is installed, but the second one -"ac3form.exe"- is not.
At the end of the wizard, there's an option saying what will be done once the installer is installed, and if open up the little window I see both .exe files listed.

maybe this is too confusing. I'm attaching the file I created. Is there any way to install both files, not only the first one?
Is it possible to install them silently or is it too tricky?
