Hi Alex,  The installation of the tools is a functionality of vCenter, and VMware would have a better understanding if there is an issue with the installation.  Their support might be able to help resolve the issue you are having.  That being said, I would like to offer some assistance if I can.  I have installed VMware tools the same way you have described.  In the past, if I had an issue installing them, vCenter would notify me of the reason why.  It would also appear as if the tools were "stripped" from the existing VM.  I suspect something similar is happening in your environment.    I cannot be certain this link applies, but we did find this from VMware.   [URL] VMware support should be able to assist you further with the installation of the tools. Unfortunately, since it is not our product, I can only offer advice on how to resolve the issue with installing the tools.  Bill
Hi, I tried to update the VMware tools version in FOV, but all that seemed to do is strip it out...  Any ideas as to how to get it back and to update it, including the virtual hardware version also? Many thanks. Alex.
