Well, you are not seeing the plugins in Vegas because you are using
Vegas 64bit and those Izotope plugins are 32bits, and you have the
VST’s files located in the default 32bit folder location and pointing Vegas to it…
That’s what throwing things off.
Vegas handles multi-track audio far better than soundforge, its what i always use.
