Handle DISM errors from PowerShell script

How can I capture errors when using DISM tool from PowerShell script?

& cmd /c 'DISM /online /disable-feature /NoRestart /featurename:[feature_name] >NUL 2>&1'

if ($LASTEXITCODE -ne 0) {
    Write-Host "ERROR"
} else {
    Write-Host "SUCCESS"
}

Whether [feature_name] exists or not, I always get ERROR.

However it works if I replace the cmd command with another, for example

& cmd /c 'dir [some_file] >NUL 2>&1'

If [some_file] exists I get SUCCESS, otherwise ERROR.

Solution

  • It seems that the exit code for success returned by DISM is 3010 instead of 0.

    This works for DISM commands within PowerShell:

    if ($LASTEXITCODE -ne 3010) {
    ...
} else {
    ...
}
