wonderware runtime v10.0 0r 10.1

I am in need of an older version of WW runtime V10.0 or 10.1, does anyone have a copy to sell or trade, runtime tag count at 5K-- ????

You can use a newer license on an older app.
For example....10.5 license will work on 10.0 developed app.

Thanks for your reply, yes I found that out about the latest version, but at 4K dollars, I was looking for someone who might have an older version to sell of maybe trade at less than 4K, -any way Thanks --
