I am using this viewer and before, I updated by downloading and updating from the Second Life Viewer page on the web.
Now it tells me that it has downloaded an updated viewer, when I log in world and asks if I want to update.
The problem is that twice, I have said yes to this and it installs the updated viewer, then, when I try to log again, it installs the viewer back to the version that I was already using, i.e. 220.127.116.114670 (64bit).
Is this a problem with the new viewer update system, recently introduced? I have noticed that the version I am using is the one still showing on the Second Life Viewers web page, for downloading.
