Do my servers and development machines have to be running 64 bit operating systems to use?
No. AspDotNetStorefront takes advantage of .NET’s capability to be architecture independent. When running on a 32 bit platform, AspDotNetStorefront will operate in 32-bit mode without ANY interaction from the user, and when deployed to a 64-bit environment, will automatically switch to 64-bit mode. No costly and time consuming upgrades are required whatsoever.
