After I have upgraded my home lab from ESXi 7.0 to 7.0 update 1c (17325551) I ran into an issue updating VMware Tools on my VMs.
I tried both update options (“automatically” and “manually”), but both failed with a VIX error.
Automatilly update output = “vix error code = 21004”
Manually update = “vix error code = 21009”
