LabVIEW 64bit v LabVIEW 32 bit for deploying executables

[SeanJ]

Hello Everybody,

I'm using a 64-bit PC but looking to deploy an executable that can used on either 64-bit or 32-bit PC's.

Does it matter if I use LabVIEW 64-bit, i.e. is it less reliable if run on 32-bit?

Rgds,

Only 32 bit executables can run on both. You should use LabVIEW 32bit anyway.

(LabVIEW 32bit has much better driver and toolkit support and is more widely used. This also makes it more stable and well-tested. It runs perfectly on a 64bit OS and can use up to 4GB of memory when running on a 64 bit OS (details).

LabVIEW 64bit is still a niche product that is only really needed if you require the gigantic address space (>4GB) that it provides.)

Thanks Altenbach,

I just installed 64-bit, doh!

Is it possible to swithch between version, i.e. have both installed?

Yes, you can install both. There is no conflict.

One little caveat is if you use dlls in your code.  If you call 32-bit dlls in your code, those vis will not compile under LabVIEW 64-bit, and vice-versa.
