Hello, we used to enroll our own installer, and we bundled both x86 and x64 into single installer
it was easy, several blocks ${If} ${RunningX64} .... ${Else} ... ${EndIf} we are going to pack NDIS5/NDIS6 the same way. in order to choose proper installer automatically, not to put that decision to user. if there's an interest, I can make some PR on that. Cheers, Ilya Shipitsin
