I'm working on something that needs to know if an arbitrary Windows registry key is a 32-bit or 64-bit key. For accessing the registry, the language I'm working in needs to know -- in advance -- if a given key should be accessed in 32 or 64 bit mode. Note that I'm not trying to determine if a given registry value is 32 or 64 (or whatever) bits; I need to know which function to use to access the key (for example, during a registry key enumeration).
So what I need is a tool that will show me this information; perhaps for example by showing 32-bit keys in one color and 64-bits in another color (but different color displays are not mandatory if there's some other way of indicating this).
I've tried about 6-7 different freeware registry editors, but none of them come anywhere close to showing what I need.
