File chossen from dialogue box is not recognized

Question

Hi All
Here I am again. I have this script that when I run it ask for remote computer name then open dialogue box to select a folder then it copy the folder to remote machine then it open up another dialogue box to select the .exe/.cmd/.bat file and Invoke it to remote computer. I am not sure it I am doing right selecting the file in Invoke command as it is giving me some error saying it is not recognized as an internal or external command. I would really appreciate some help from all of you expert out there. Thanks a lot in advance. Here is my code ....

$Computer = Read-Host -Prompt "Enter Computer Name"  
$folder = Test-Path -path "\\$computer\c$\setup"  
IF (Test-Connection -BufferSize 32 -Count 1 -ComputerName $Computer -Quiet) {  
  
       Try {  
              if ($folder -eq $true) {  
  
  
                                  Try {

                                            $foldername.rootfolder = "MyComputer"  
                                            $foldername.SelectedPath = $initialDirectory

The error message is like this....

'\filename.exe' is not recognized as an internal or external command,
+ CategoryInfo : NotSpecified: ('\ed101ridgetop...ternal command,:String) [], RemoteException
+ FullyQualifiedErrorId : NativeCommandError
+ PSComputerName : k8xd0201421

operable program or batch file.  

Answer 1

The variable $filename contains only the value "filename.exe", but the working directory (which appears to be the root directory "\") and the contents of the PATH environment variable on the remote machine don't contain the directory in which "filename.exe" can be found.

Answer 2

Use "Copy-Item" to get the destination path, like:

$copy = Copy-Item -Path $a -Destination "\\$Computer\C$\Temp\" -Recurse -Force -PassThru | Out-Null  

Now you can use $copy to Invoke the cmd.

Invoke-Command -ComputerName $Computer -ScriptBlock {& cmd.exe /c '$copy.Fullname'}
