Issue/Introduction

An error was encountered when attempting to connect to the vCenter through PowerCLI after installing the PowerCLI modules.

Connect-VIServer : Could not load module

Environment

vSphere 8.0.x

Cause

• PowerCLI module will not load correctly.
• According to the documentation, PowerCLI modules must be unblocked before use. It appears the modules were not properly unblocked, leading to the issue.

Resolution

• Verify that the PowerCLI modules are extracted and placed in a folder included in the PowerShell module path ($env:PSModulePath).
• Move the extracted module files to another folder containing PowerShell modules and unblock the files using the following command:

  cd <path_to_powershell_modules_folder> Get-ChildItem * -Recurse | Unblock-File

• Post making the above changes, should be able to connect to the vCenter server using PowerCLI.
