Hello,
Check the format. Here you are simply running "echo" command. So you are just running the command. Just remove the "ScriptType bat" portion and it should run fine.
If you want to run a remote PowerShell format then the format of the passed command should be:
$script = '&"$env:ProgramFiles\Common Files\Microsoft Shared\MSInfo\msinfo32.exe" /report "$env:Tmp\inforeport"' Invoke-VMScript -ScriptText $script -VM VM -GuestCredential $guestCredential
Runs a PowerShell script. In PowerShell, to access environment variables, you must use the following syntax: $env:<environment variable> (for example, $env:ProgramFiles). Also, to run the program, you must specify an ampersand (&) in front of the program path.
The outer quotes ($script = '...') are required because this is how you define a string variable in PowerShell. The inner double quotes are required because there are spaces in the path.
Similarly if you want to run a remote Batch script then the format is as given below:
$script = '"%programfiles%\Common Files\Microsoft Shared\MSInfo\msinfo32.exe" /report "%tmp%\inforeport"' Invoke-VMScript -ScriptText $script -VM VM -GuestCredential $guestCredential -ScriptType Bat
Runs a BAT script. In BAT scripts, to access environment variables, you must use the following syntax: %<environment variable>% (for example, %programfiles%).
The outer quotes ($script = '...') are required because this is how you define a string variable in PowerShell. The inner double quotes are required because there are spaces in the path.
So when you specify the scripttype as "Bat" then you need to follow the syntax as well.
At the end, in your example just do not specify any "ScriptType" parameter and it should run fine.
