VMware Tools ISO image does not exist or is inaccessible

Hi,

I am running ESXi as a trial on my NUC. When I try to install VMWare Tools to my Windows 2012 r2 server it says image does not exist or is inaccessible. I'm not sure why the tools can't install. I have looked at the file system and all the symbolic link paths. The tools aren't there. How can I install them and where should they go?

I am running

Version:

1.8.0

Build number:

4516221

ESXi version:

6.5.0

ESXi build number:

4887370

Thanks in advance
