CS6 Update Failed

I've been a Creative Cloud customer from the start, and bought the products before CC existed.  I still run CS6 on an older laptop, but the update (via CC) has always failed.  I can not find any way on the Adobe website to submit the details from the install log, so I'm copying the relevant parts here because it's the only wat I can see to send it to the Abobe website.  If this is inappropriate, please direct me to a better point of contact:
