Install-Module -Name VMware.PowerCLI throws PackageManagement\Install-Package : Authenticode issuer

Recently I tried to install VMware PowerCLI for scripting some tasks for ESXi but got this error.

Get-Modules doesn’t show anything. That was strange.

I checked the Powershell Modules folder and found that on this host was an old installation.

I have deleted all folders and re-checked if the operation was successful.

Afterward, I retried the installation and it was completed without issue.

P.S. Don’t forget to use the -AllowClobber parameter to avoid cancellation of installation due to existing cmdlets from the Hyper-V module.
