For me the upgrade to Beta 3 didn't install automatically.
I saw the warning sign saying it was downloading. It downloaded, then nothing happened apparently.
I restarted Verbum, and the little warning sign appeared, but no pop-up info was available when hovering the mouse over it. It just sat there. Update now didn't do anything more. Still on Beta 2.
Looking through the logs, it looks like the update process was failing. Maybe related to the faulty Verbum.exe in the Verbum folder, as it seems the update process was calling that file.
I found the installer in the Verbum folder and installed it from there. It installed fine. However, the Verbum.exe in my Verbum folder still doesn't do anything (the EXE file in the System folder continues to work correctly). I'm now running Beta 3.
Logs from before I manually ran the installer:
