Unable to run the parametrized batch file on remote machine using PowerShell - powershell

Question

Execute the remote server parametrized batch file from PowerShell.
Doesn't throw an error nor executed command on remote machine.
$path = "D:\run\test-5.2.bat";
Invoke-Command -ComputerName testserver -Scriptblock { "$path" }
Script inside the bat file is msiexec with parameters, which shall execute through Command Prompt only.

Answer 1

Based on this msdn link, you can run a ps1 script file on remote computers. So if it is possible to "port" the content of the bat file in a ps1 it should work. Here is the msdn example:
Example 11: Run a script on all the computers listed in a text file
PS C:\> Invoke-Command -ComputerName (Get-Content Servers.txt) -FilePath C:\Scripts\Sample.ps1 -ArgumentList Process, Service
This example uses the Invoke-Command cmdlet to run the Sample.ps1 script on all of the computers listed in the Servers.txt file. The command uses the FilePath parameter to specify the script file. This command lets you run the script on the remote computers, even if the script file is not accessible to the remote computers.
When you submit the command, the content of the Sample.ps1 file is copied into a script block and the script block is run on each of the remote computers. This procedure is equivalent to using the ScriptBlock parameter to submit the contents of the script.
Hope that helps

$path is a string. PowerShell simply echoes bare strings instead of executing them, unlike CMD or bash. Use the call operator (&):
& "$path"
or Start-Process:
Start-Process cmd.exe -ArgumentList '/c', $path -NoNewWindow -Wait
to have PowerShell execute a string as a command. Since you say you're running msiexec.exe from the batch script using the latter may be required.
On top of that you have a scope issue. The variable $path inside the scriptblock is not the same as the one in the global scope. You can mitigate that via the using: scope qualifier:
Invoke-Command -Computer testserver -Scriptblock { & "$using:path" }
or by passing $path as an argument to the scriptblock:
Invoke-Command -Computer testserver -Scriptblock { & "$($args[0])" } -ArgumentList $path
