If you had to choose between the following two options which would you choose and why?
Option A
A single 60 MB .NET Framework Redist Installation package that installs on all 32 and 64 bit platforms.
Option B
A 20 MB .NET Framework Redist that installs on x86
A 40 MB .NET Framework Redist that installs on IA64
A 40 MB .NET Framework Redist that installs on AMD64
I'm curious as to what people think about this and why each option is preferable.
