Why does start-job cancel previous job when starting the same exe?

Question

I want to execute same exe with different, parallel arguments each time in a loop.

So I decided to use Start-Job, but when I try it, I realize that when the second instance starts, the first is cancelled:

foreach($name in $insanceNames)
{
   Start-Job -ScriptBlock { & "C:\program.exe" $args } -ArgumentList /instName,$name
}

When second instance is started, the first one is interrupted with no errors.

If I execute the same program, in parallel, through two consoles manually, I don't have this problem.

NOTE: I cannot start program just with "&" because I need to run them without waiting previous instance finishes.

Answer 1

Finally I changed Start-Job for Start-Process and it works as I expected.

I was looking for the difference between both in this post and i don't understand why Start-Job stops previous instance and Start-Process keep all the intance as expected.

However, I solved my problem.
