I have downloaded the upgrade today following links. After downloading the file I found that it was build 2257 while the latest build was 2259 which was available as per site since 23rd September. I had to download the entire 37 MB a second time. It is surprising that an update made available on 23rd Sept cannot be downloaded directly even on 27th September. Acronis should look into it so that at least the latest build is always available for download.
