imaq shift 16to8 bit not working in 64bit

[KimT]

Hi,

I installed Labview 2009 64bit.

I'm using an application written in 32bit labview. I want to convert it to 64bit. I get 1 error: the subvi "IMAQshift 16to8" : Call Library Function Node: Function not found in library.

How can I solve this???

Do I need to install Vision 64bit? Where can I find this?

Greetings

Hello Kim,

There is indeed a LabVIEW version which is 64 bit native. But all the modules are not yet 64 bit. You cannot install a 32 bit module on a 64 bit LabVIEW install. You can, however, install the 32 bit version of LabVIEW on a 64 bit OS which will then run in the emulation layer (WoW layer). Then you can also install the modules. But you will not have the advantages of the 64 bit OS since they run in the 32 bit layer.

Hope this clears it up.

Hi Rik,

I found on the NI site (http://zone.ni.com/devzone/cda/tut/p/id/10184) that the vision module is already available for 64 bit!

Thanks

Hi Kim,

You are completely right! That one went by me, I was assuming that the 32 bit restriction applied on all modules. Sorry for that. I dug a little bit deeper and found out that there is only one isntaller for the Vision Development Module. When you install it you have to tell the installer what support it should install, see following link:

Hope this helps, if it still not works let me know!
