This should do the trick:
$executingScriptDirectory = Split-Path -Path $MyInvocation.MyCommand.Definition -Parent

$0 = $myInvocation.MyCommand.Definition
from there, we can get
$dp0 = [System.IO.Path]::GetDirectoryName($0)

I have created a powershell script and you can use its function Get-ScriptDirectory to get the current folder and then use that folder as a variable and append it before setup.exe
You can get the script here.

Hey, you should really try to get some exitcode handling in that script. Also, you can use the code:
$install = start-process -filepath "msiexec.exe" -argumentlist '/i "foo bar 1.0.msi" /qb!' -wait -passthru
instead of [Diagnostics.Process] to launch your setup. Easier to read and use unless you are a .NET Developer.
Just type $install | get-member and you'll see ;) - Ifan 12 years ago
