I think that setting resides at the virtual directory level in IIS6 (see screenshot) at link here

The first ASP.Net application to start in the App Pool will determine the .Net Framework version used. If you want to run ASP.Net 2/3/3.5 apps on the same IIS6 as ASP.Net 4 apps, put them in separate app pools.
