Powershell script is not executing EXe remotely on list of servers paralelly RRS feed

  • Question

  • Hi,

    I have created a script to execute an EXE on list of remote servers parallelly. The command is getting executed without any issue, but EXE is not running on remote servers.

    Can anyone help me to correct the script ?

    Set-ExecutionPolicy unrestricted -force
    ForEach ($Computer in Get-Content C:\server.txt)
        echo "$Computer"
                        Invoke-Command -AsJob -ComputerName $Computer -ScriptBlock {& 'c:\windows\WUInstall.exe' /install /reboot}

  • Within your script block, you could try using Invoke-Expression (I've used it quite a bit successfully for running remote commands)

    ForEach ($Computer in Get-Content C:\server.txt)
           echo "$Computer"
           Invoke-Command -AsJob -ComputerName $Computer -ScriptBlock {

          Invoke-Expression -Command "c:\windows\WUInstall.exe' /install /reboot"


    Alternatively, you could use a PSSession instead of ComputerName

    ForEach ($Computer in Get-Content C:\server.txt)
           echo "$Computer"

          $PSSession = New-PSSession -ComputerName $Computer
           Invoke-Command -Session $PSSession -ScriptBlock {

          Invoke-Expression -Command "c:\windows\WUInstall.exe' /install /reboot"


    Good luck!

  • What is WUInstall?  It is not part of Windows.  You cannot run a GUI app remotely.  Many apps cannot be run remotely.  Contact the vendor of the app to find out is this can be done.

  • WUInstall.exe is the tool to install patches by contacting the correspondent WSUS server in each region.I have edited my script like below even this is giving error

     ForEach ($Computer in Get-Content C:\servers.txt)
    #To enable winrm if not already
    $result = winrm id -r:$computer 2> $null
        if ($lastExitCode -eq 0) {
        Write-Host "WinRM already enabled on" $computer "..." -ForegroundColor green
        } else {
        Write-Host "Enabling WinRM on" $computer "..." -ForegroundColor red 
         \\slcmpx\c$\windows\system32\PsExec.exe \\$computer -accepteula -s C:\Windows\System32\winrm.cmd qc -quiet 
        if ($LastExitCode -eq 0) {
            \\slcmpx\c$\windows\system32\PsService.exe \\$computer restart WinRM 
            $result  = winrm id -r:$computer 2>$null
        if ($LastExitCode -eq 0) {Write-Host "WinRM successfully enabled!" -ForegroundColor green}
            else {Write-Host "WinRM not enabled!" -ForegroundColor red}
           } #end of if
        } #end of else  
           echo "$Computer"
          Invoke-Command -ComputerName $Computer -ScriptBlock {Set-ExecutionPolicy unrestricted -force}
          $creds = Get-Credential
          $PSSession = New-PSSession -ComputerName $Computer -Credential $creds -Authentication Credssp
          Invoke-Command -Session $PSSession -ScriptBlock {Invoke-Expression -Command 'c:\windows\WUInstall.exe /install /reboot'}

  • Always solve the first error in the list and retest.  Do this until you fix all errors.

  • Invoke-Command does not require a session.  Why use both PsExec and WinRM?

    You are making this way to complicated.  Start small and get one piece at a time working.

    WUInstall cannot be run remotely.  WU is restricted to interactive or system installs only.

    You cannot remotely set execution policy.  Use Group Policy.
