I am sure others have game installed on D or other drive and no issues. How hard would it be to move to C drive? Reason I ask, the other day I was trying to install .msi program from D drive. If never would start. On a whim I moved it to C, and it went on system right away. Your hardware looks good, assuming SSD is plugged into 3.0-3.1 USB port, if not anything slower could be culprit. Make sure. And as one thing, had USB HDD which would never open when I plugged it in, deleted all the USB ports and let windows find them all again on restart, drive worked, so USB drivers get messed up once in while. Post this bug on Zendesk as well, believe on this one you will get some help.
