When running Orature 1.9.1+6281 in Windows, if I check for updates I'm given the link: http://nightlybuilds.s3-website-us-east-1.amazonaws.com/Bible-Translation-Tools/Orature/release/orature-windows-x64-3.1.34%2010075.exe/
Unfortunately, this link does not provide any downloadable content, and certainly not an updater.
