I get a similiar bubble window saying the same thing, that the update could
not complete. I installed Windows Defender, but it won't update. I do have
the Windows Firewall and Automatic Updates turned on. I guess this is what
happens when installing beta software.
I should know better.......now I have nothing it uninstalled the former
version also.
I uninstalled it , ripped the remnants out of the registry and it still
doesnt update. Also shut of updater and the firewall no luck.
