I am getting installation errors when the demo data is loaded by the installable program using the installation wizard.

Till that time the installation work fine though we get errors some times we resolve the same.

The demo data does not come and it causes problems to set up the new company all alone

The error message would be particularly useful along with the pertinant logfiles, database info, anything special you're doing (like trying to install a Multibyte language) <etc>.
