Hello there, supermanDan and others,
I was having the same problem on a W7 x64 VM in vSphere 6.0.
The VMware Tools were reported as being "Running (Not Current)", but within the OS the installed software list showed no sign of VMware Tools being installed at all.
The problem could be solved by simply re-running the installer (without the need to rename or uninstall) interactively while I was logged on on the machine. After a reboot everyting was fine, VMware Tools are now reported as "Running (Current)" within the vSphere Client (C#) and the Web Client and the behaviour is back to normal.
