New Post: How does ClearScript choose which dlls to use? (x32 or x64)

I'm using ClearScript with the V8 engine and I'm noticing that it's always using the x32 dlls ClearScriptV8-32.dll and v8-ia32.dll. These also require the VC++ redistributable package for x86 machines. ClearScriptV8-64.dll and v8-x64.dll don't seem to be touched, and I'm not sure if these would require the x64 VC++ redistributable instead.

Can I rely on (or configure) this behaviour and not bundle the x64 dlls or the x64 VC++ redistributable to lower the size of my distributed software?
