respectfully, that answer is not much help at all. What exactly does "hosted VMware products" mean and what does it have to do with a VMware Fusion user not being able to find and use 'vmware-vdiskmanager'?
Why not say something like, "The 'vmware-vdiskmanager' is no longer installed with Fusion 5.x. It can be downloaded from X."
Searching the VMware site for where to get 'vmware-vdiskmanager' turns up nothing. I don't know about 'dehidding' but we're trying to rename existing virtual disks. There's no 'vmware-vdiskmanager' tool anymore and there's no UI provided to do this. Why does VMware inconvenience their registered users like this?
