I've writing Direct2D application and I want to distribute it.

Then I've considering how to distribute d2d1.dll manually because the latest DirectX Runtime will not install d2d1.dll on the windows\system32 directory.

Can we setup SxS for Direct2D or DirectX manually and distribute related dlls manually with own application ?

In addition DirectX SDK will put d2d1.dll on windows\system32 directory correctry, but this size is over 500MB.
It seems large and this works could annoy users.
