First thing to do in case when a message about a corrupt file is reported (either the MSI itself, or some component, like error 1335) is to check the integrity of the downloaded package. It has been reported that some downloaders/browsers may reliably fail to download some versions of packages properly, while using a different software for download resolves the issue (e.g., tdf#121749). To check if your downloaded file is correct or not, you need to use a software that can calculate checksums of files (7-Zip can do that, as well as this Microsoft tool). The correct checksum values are available from LibreOffice Download page, using Info link below the Big Download button.
