The term 'choco.exe choco.exe' is not recognized as a name of a cmdlet, function, script file, or executable program.

Whenever you use Get-Command to find a command, you must ensure that you only get one result back.

Chocolatey/source/public/Install-ChocolateyPackage.ps1

Line 300 in bd094df

if (-not ($chocoCmd = Get-Command 'choco.exe' -CommandType 'Application' -ErrorAction 'SilentlyContinue'))

Otherwise, if (for instance) something modifies your Env:PATH and appends the chocolatey path a second time ...
Let's say, hypothetically, that one of these has extra slashes, or the wrong slashes or a slash on the end:

Chocolatey/source/public/Install-ChocolateySoftware.ps1

Lines 271 to 274 in bd094df

	if ($($env:Path).ToLower().Contains($($chocoExePath).ToLower()) -eq $false)
	{
	$env:Path = [Environment]::GetEnvironmentVariable('Path', [System.EnvironmentVariableTarget]::Machine)
	}

You'll end up getting the error " The term 'choco.exe choco.exe' is not recognized as a name of a cmdlet" down here:

Chocolatey/source/public/Install-ChocolateyPackage.ps1

Line 327 in bd094df
