This is my code updated. This is working using PS ISE, but I tried execute it from WinPE environment, It shows those error above.
Could anyone help me please. Thank you

Answer 1

this works ... but i think the use of LoadWithPartialName has been deprecated. i can't find the "new way" at this time, tho. [blush]
[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") |
Out-Null
$SelectFileDialog = New-Object System.Windows.Forms.OpenFileDialog
$SelectFileDialog.InitialDirectory = 'c:\temp'
$SelectFileDialog.Filter = 'Extensionless files (*)|*'
$SelectFileDialog.Title = 'Please select a file and then click [OK]'
$SelectFileDialog.ShowDialog() |
Out-Null
$SelectFileDialog.FileName

Answer 2

I believe it'll work if you remove | Out-Null from this line
$OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog | Out-Null

Answer 3

Just need to add this, it works well.
Thank you for all the contribution
$OpenFileDialog.AutoUpgradeEnabled =$false
