I have often got to interact with customers who had an issue getting the NSX VIB installed on their ESXi host. Most of the time, it is a tedious configuration issue or a step that they have forgotten. I have hit a similar issue today in my lab with me missing a simple step and wanted to share the error and the fix with others just in a hope it helps others recover from the same error quicker.
I was getting the following error every time I tried to install the NSX 6.4.5 VIB on my ESX 6.7U2 host, and similar error as well when I try to run the resolve button.
