Hi,

In the root of the PSAppDeployToolkit zip file, there is a file named PSAppDeployToolkit.pdf, within here you can find what Environment Variables are defined in the PSAppDeployToolkit (see Page 54 in the v3.9.3 version)

You can also set these using native PowerShell commands - here are a couple of earlier discussions around the same subject:

Set New System Environment Variable and Update or Append PATH variable

I have to do these 2 actions from PSADT- version using 3.8.4. Set System Environment variable: Currently I am using this method to set the variables however logging is not happening since I’m using the native PS method.

I used the command [Environment]::SetEnvironmentVariable(‘PATH’, $env:Path + “;$envProgramFilesX86\JDK”,[EnvironmentVariableTarget]::Machine) But required path is appended to registry.But the issue is one more entry also added which is not required.

C:\Users\ank\AppData\Local\Microsoft\WindowsApps;C:\Program Files (x86)\JDK

That’s the problem with editing %PATH%.
it’s very easy to make code to ADD to %PATH%
It’s hard to make code that will not make %PATH% grow with with dupes and dead paths.

I tried years ago and failed.

I’m sorry I can’t remember where I copypasta’d this so I can’t give credit, but this is the function I use…

## Set PATH environment variable
Function Set-PathVariable {
    param (
        [string]$AddPath,
        [string]$RemovePath
    )
    $regexPaths = @()
    if ($PSBoundParameters.Keys -contains 'AddPath'){
        $regexPaths += [regex]::Escape($AddPath)
    }

    if ($PSBoundParameters.Keys -contains 'RemovePath'){
        $regexPaths += [regex]::Escape($RemovePath)
    }
    
    $arrPath = $env:Path -split ';'
          Write-Log -Message "Previous PATH was: $($env:Path)"
    foreach ($path in $regexPaths) {
        $arrPath = $arrPath | Where-Object {$_ -notMatch "^$path\\?"}
    }
    $PathUpdate = ($arrPath + $addPath) -join ';'
    Write-Log -Message "Updating PATH to: $($PathUpdate)"
	
	[Environment]::SetEnvironmentVariable("PATH","$PathUpdate","Machine")
}
Set-PathVariable -AddPath 'C:\Add\This\Path'
Set-PathVariable -RemovePath 'C:\Delete\This\Path'
