There is an error when I want to reinstall the applications that came with my mac (after having reinstalled the Mac OS X DVD). What can I do?

I erased my hard disk and then installed the Mac OS X DVD. After having done this I wanted to install the applications too, for which I introduced the Applications DVD. The DVD is recognized and I follow the instructions given. On the last step, the installation, the Installer shows me a Message. It says that there is an error, and that I should contact the Software developer. It is very weird, because there is no error number or any other explanation. If somebody could help, I would be enormously thankful.
