What context are you in? SP2 is when the version of fusion.dll in the framework
folder has a 288 patch (1.0.3705.288). In a setup project you might be able to
use the MsiNetAssemblySupport property as an explicit launch condition, so the
technique to get that .NET version depends where you need to find out.
