This problem (0x80070570) has been reported a few times:

However I haven't seen a fix for it. It is apparently due to problems
with corrupted files or with broken hard disks or something. I don't
remember hearing of this problem before Python 3.5 and AFAIK it only
occurs with 3.5.

Could you try installing 3.4 and let us know if that works? If so it
may be a bug (I don't see any tracker issues for it yet).
