To check it, you need two things:

The checksums for all the LO downloads are available on the "Info" page of every download. Take care to get the checksum for the specific file you've downloaded - OS, LO version, Language, Program or Help pack.
• have read and write access to the downloaded file. If you choose "Run downloaded file" or something like that directly from the browser's download dialogue, installation may fail if the browser saves the download read-only. So, you should choose "Save locally" or "Save on local disk" in your browser's download dialogue to save the download, and then open the download directory with Windows Explorer and run the file from there.
