Sometimes the following error appear while starting VMware vSphere PowerCLI:

Get-PowerCLIVersion : The term 'Get-PowerCLIVersion' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the name, or if a path was

To solve this issue try to start Powershell as administrator and run the following commands (they will add PowerCLI modules to the global variable on the system level):

$CurrentValue = [Environment]::GetEnvironmentVariable("PSModulePath", "Machine")
[Environment]::SetEnvironmentVariable("PSModulePath", $CurrentValue + ";C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI\Modules", "Machine")
