64 or 32 for MAC

[William Humphrey]

I know I asked this question before but I can't find the answer in my emails.

1. vStudio and v4rev are only available as a 32
2. vServer is only available as a 64

Does it make any difference to mix them? I am running 10.7.3 on mac os and LiveCode 5.5

Please do your best to give me a clear "best practice" for what files I should download. It seems to me that everything should be "64" but it isn't possible because of what you have available.
