VI Logger and Labview

[421939126]

Hi,

Could someone let me know if I can install simultaneously two different versions of Labview in one computer, say 7.0 and 8.5?

I need Labview 7.0 for an application (.vi), however, I also need a newer version of labview to use with a VI Logger. The application is a little bit complicated so I dont really want to rewrite it, do not know much anyway.

Thanks a lot

Yes, you can.  Key thing is to install the older version of LabVIEW first.

Hi Vinh,

I just wanted to expand a little on Ravens reply.

You can install multiple versions of LabVIEW on the same machine - I have (7.1,8,8.2,8.5.1 and 8.6) LabVIEW. However, two areas which may cause issues:

1#: Toolkits/Modules: Installing Toolkits for Use with Multiple Versions of LabVIEW. Please see the KnowledgeBase link for more information.

2#. Drivers - some only support certain versions of LabVIEW, so just be careful when using certain drivers to check if they support both versions - because you certainly can't have more than one installation of a driver. I think with 7 and 8.5 you should be fine though (For DAQmx anways).

Note: I noticed your upgrading to LabVIEW 8.5 - but some toolkits only support certain versions also. For LabVIEW 8.6 particularly alot of toolkits where updated to support LabVIEW 8.6 and therefore the newer version of the toolkit it required.

Hope this helps,

Thanks Ravens and Hillman,

Being more spaecific, I have to use Labview 7.0 and DaqMX 7.0 for an vi application (required DaqMX 7.0 vi library, otherwise it goes wrong).

Besides, for data logging, I need to use Measurement and Automation 4.0 and DaqMX 8.3 or newer for the VI logger.

So the problem comes from DaqMX, not Labview.

What should I do?

Sorry for these simple questions, I'm just a starter 🙂

Hi Vinh,

Thanks for the reply and I hope your well.

The issue is you can't install more than one version of the DAQmx driver.

This knowledgebase article,

NI-DAQ & LabVIEW Version Compatibility (for Windows)

http://digital.ni.com/public.nsf/allkb/97D574BB1D1EEC918625708100596848?OpenDocument

explains which versions of the driver support which versions of LabVIEW.

Unless you can get a driver which supports both old and new applications you will have to upgrade one aspect of your applications.

Let me know if you have any questions,
