Need help with Windows Vista

[south gurl]

I am having problems with installing certain applications off the internet. Windows Vista is always telling me that publisher is unknown, but when I try to install again the publisher shows up but I still can't install.  Then sometimes it will say not a valid win32 application or something like that
