After installing or upgrading to Acronis Access Advanced 7.2.x and newer, LibreOffice will also be installed. If you uninstall LibreOffice, the Acronis Access Tomcat service will become unreachable at the next startup and you will not be able to open the web interface.
Web Previewing of files is a new feature introduced in version 7.2 of Acronis Access Advanced which requires LibreOffice to render the previews. This means that LibreOffice will always be installed with recent versions of Acronis Access Advanced.
