I have installed SP2 on three of my sites. On the fourth site, it has failed three times so far. The site has a 20Mb/s Internet connection. I initiate download using management console. It logs Chrome out of the site and starts downloading servicepack.zip to C:\ProgramData\3CX\Data\Updates. The download size gets to about 20MB and never finishes. I have re-started all services and indeed the whole server but still get the same problem. I also tried clearing the browser cache.
