Can't install

I am trying to install the spreadsheet program but I keep getting the following error after it creates the database successfully.

Not Found

The requested URL /spreadsheet/samples/01_simple_init.html was not found on this server.
Apache/2.2.22 (Ubuntu) Server at 192.168.2.6 Port 80

Any ideas?

Hi,
please, make sure that installer has rights to write files in spreadsheet directory.
