zone doctor vs. LE Rogue

also what is the difference between ce 64 and 86? if both can load on my computer will it make a difference which one i use?

It won't make much a difference. x86 (32bit) programs can run on both 32bit (native mode) and 64bit (emulation) versions of Windows while x64 (64bit) can only run on 64bit version of Windows. 64bit programs can access much more memory, can manage way more data, etc but this usually doesn't matter with small programs like all FF6 editors and hex editors we use. Programs that requires a lot of memory and lots of process are usually 64bit only these days.
