I installed the upgrade from 3846 and let installer work its magic. It proceeded to update parallel tools in my Windows 7 vm and failed. Using Windows system restore back to prior event and manually removing parallel tools doesn't even work. Now I have a vm that has only certain features working. No matter how many times parallel tools install is run, it fails. So I go with a vm that needs a parallel tools upgrade (no available share folder) or I go with the upgraded parallel tools partially working. Ideas?
