[HELP] - nvidia grid vib install fails

I'm trying to install the nvidia grid vib in my esxi 6.5 for a grid k2.

I'm following the instructions from nvidia to the letter but nope...

I run the following command:

esxcli software vib install -v /etc/vib/NVIDIA-vGPU-kepler-VMware_ESXi_6.5_Host_Driver_367.134-1OEM.650.0.0.4598673.vib

I get the following error:

[InstallationError]

Error -3 while decompressing data: invalid literal/lengths set

     vibs = NVIDIA_bootbank_NVIDIA-kepler-VMware_ESXi_6.5_Host_Driver_367.134-1OEM.650.0.0.4598673

please refer to the log file for more details.

What is the problem? this is a fresh esxi install. I just downloaded the vib directly from NVIDIA I expect that following the instructions would lead to completion...

Thanks for any help...
