Did you do all Windows updates?

You need the dll mentioned in the error message, and you won't get it by 
repeatedly installing Python (I don't know why the message tells you to 
do that ...). You will have to get it from Microsoft instead. Googling 
the name of the dll will probably lead you to it quickly, the problem 
seems to be quite common.
