Should I expect my build to work on 64-bit windows?

Unity Engine

I’m using Unity on 32-bit Windows Vista, and I see that some people use it on 64-bit Windows with varying success.

What I didn’t find in my searches is whether Unity’s built executables are supposed to be able to run on a 64-bit o/s like Windows Vista 64-bit, Windows 7 64-bit and OSX Snow Leopard 64-bit?

Will the 12% or so of 64-bit Windows users not be able to run my application? I did try running a 32-bit built app on a 64-bit Windows Vista and it kept saying it couldn’t find the accompanying data folder.

I’m sure it should at least work on Windows 7 Ultimate because it has the ability to run any program under any other of its os’s (You can run an XP-only program in windows 7).

Is it proven? And what about vista? What is the official word from UT?

My builds do. 99% of 32 bit applications still run on 64 bit windows, but don’t take advantage of the 64 bit performance increase unless they are made specifically for 64 bit.

i’m running vista 64 bit and all my builds work on it.

working here fine on win7 64bit and worked before on Vista 64.

Did you potentially add an own assembly?

Oh. Well Unity was doing something strange not finding its data folder but it might be that I renamed the app or something. I rebuilt without changing the name and it worked fine. But one other part of my app had a bit of a problem - it’s code from another language I suspect is doing something fishy.

Well, good to know it’s supposed to work so that I can figure out what’s going on. Thanks.
