I had v5.30.6063, the problem started with the version prior to 6063.
I have manually downloaded the builds, I did that last time and this time and they seem to install without problem retaining my registration information.
I just think it would be very convenient if I could update from within the program as I have done in the passed.
I tried turning off Windows Firewall when checking for updates, it didn't help.
If you've been having issues with it not automatically updating by itself perhaps visit the Microsoft Updates/Windows Updates site, and download any update that states it's for Root Certificates. Sometimes updating Root Certificates when an update is available may fix the issue.
