I opened my Paint.NET program today, after not using it for some time, and got a notification there was an update. I chose to Install on Exit, and let it download in the background. I then closed the program, and it told me it would install the update now; "Optimizing, and installed successfully". Opened the program back up, and it appears to have worked properly.
Glad you found the solution for your problem. :)
That's how I've successfully updated in the past.
I won't update "now" from now on.
Cheers!
