Libre office refuses to install

it is Vista. Right click on the downloaded file, select the Install option, but nothing happens

Do you have the option to install as administrator?

VI$TA still lives on … Can’t you just double-click the installer and choose an unprotected area such as your user folder where you install ? Your other option is using a portable edition by PortableApps.com, based on the Fresh branch: http://portableapps.com/apps/office/libreoffice_portable
