Issue:
When installing PowerChute Network Shutdown OVA files on VMware ESXi 6.7 Update 2 the web client may crash or the VM after deployment cannot be powered on.

Product Line:
PowerChute Network Shutdown

Environment:
VMware ESXi 6.7 Update 2

Cause:
Known issue with Update 2
See VMware Community thread https://communities.vmware.com/thread/609629 and VMware error report https://labs.vmware.com/flings/esxi-embedded-host-client/bugs/851

Solution:
 

Updated ESXi 6.7 to latest patch release resolves the issue.

Client version:1.33.3
Client build number:13454473
ESXi version:6.7.0
ESXi build number:13644319

Or:
Install the OVA using PowerShell.

Launch PowerShell:

• Install Module -Name VMware.PowerCLI
• Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false
• Connect-VIServer -Server <ESXi Host IP> -User <Username> -Password <Password>
• $ovfpath = "C:\Users\Temp User\Downloads\PCNS_4_3_vapp_en.ova"
• Import-VApp -Source $ovfpath -Name "PCNS43App" -VMHost <VM host IP> -Datastore <datastore name> -DiskStorageFormat thin

You will change ESXi Host IP to the ip of your host. Change Username to the username you use to login. Change Password to the password you use to login. Change the path to match where you have stored the PCNS OVA and change datsore name to the name of your datastore. You can also change the name of the new VM i.e. PCNS43App to what you would like to name the new VM. Example instead of PCNS43App the new VM could be named PowerChute43Appliance.
