Jim, Well, the most likely answer is that she has a lot more user data on her system, and if this is the case then you are in luck. You can always get a USB drive or microSD card that's as large, or larger, in its capacity than the whole "hard drive" on this machine. Copy off all the user data and then delete it from the tablet itself. Then run the upgrade, which will likely work. Then copy the user data back on to the device.
I actually suggest that, whenever possible, if your tablet has an SD or microSD card port that you keep one in there and save all your user data to that rather than to the "hard drive" (which isn't, but you know what I mean). These days 32GB isn't a heck of a lot of space as far as any OS is concerned. The microSD card I have in my smartphone is 64GB. Brian
