Okay, so no "escaped quotes" are actually being passed to system(). I was confused by your reply to phigan.
The end result (passed to system()) looks like it would be:
""C:\Program Files\Path\To\Program" some-arg "some-arg""
That's pretty weird.
One nice thing about JavaScript is you don't have to escape the double-quotes if you inclose the string in single-quotes. So could probably get away without escaping anything.
