No, it's so that servers aren't overloaded and i'm sure also a good way to avoid meltdown at support in case some issue not seen in testing suddenly affects a large part of users. I get the updates last always 1-2 weeks later and so what? I can just download the installer and update in a couple of minutes if it's important to me.
Obviously something may be up in your case so i would update manually and if this was originally an older installer perhaps even installed as version 4 i would uninstall, reboot and install 5.5.1012 fresh.
Isn't that exactly what I said but in a different way that there may be a problem with the update and so there is a delay before it is rolled out? But surely there are beta testers . Either way that is a long time to wait for any updates from Version 18.104.22.1682 to Version 22.214.171.1246. It has been almost a month since the date on the 126.96.36.1996 update was created. I ahve had to moanually update. That required a re-boot. Although I was able to copy the files after stopping the SAS Service on another PC. Why the setup file cannot do I don't understand?
