Update bug still present Windows 8.1 64 bit:
Only Code 9 this time, on update v1.07972
Different tries get stuck at different points 0, 2, 4, 7, 9% were ones I saw.

Upon closing and reopening, the auto update made it to 100% but threw code 2 and 9 errors.

I get the following errors when trying to update from the about menu, or auto update from startup.
