Please describe the steps you took and the error message in more detail, otherwise it is very hard to help.

I start the installation file. It start with “Verifying the Installation”, and then I get a message with this Error.
"
Error 1704. Installing Mitsrosoft Office Professional 2010 suspended. You must undo the changes made ​​by the installer. You want to roll back the changes?

These types of error messages usually mean there is a problem with a prior installation e.g., not restarting the computer when prompted. You may need to download a utility to remove all trace of a prior install. Which version of LO were you installing?

I downloaded the file here http://www.libreoffice.org/download/?type=win-x86&lang=de&version=4.2.0
