Can I run a Labview 7.0 exe on win95/98 at the same time a LV3.x VI is running (using LV3.x development system)?

[User002]

Hi Folks...

I have an ancient LabVIEW 3.1 application that is running on Win95. It is not and executable, rather it is a VI (with many associated VIs) that runs from the development system. This has become an important manufacturing application but the data processing needs to be revamped.

I want to develop a LabVIEW 6.1 (or 7.0 I guess) application and install it on that machine as an executable.
1. Will Win95 run the LVRT and the LV 6.1 or 7.0 executable
2. Will it be ok to have the LV3.1 (with development system) running concurrently with the LV6.1/7.0 exe?

Thanks in advance!

You can't run 7.0 on Win95. LabVIEW 6.1 was the last version to support that OS and LabVIEW 7.1 drops support for Win98 and ME. Aside from that, you might be able to run a 6.1 exe and the 3.1 development system on the same computer. You will have to be careful about hardware drivers though. If you install the versions of NI-DAQ or NI-GPIB (for example) that come with 6.1 or later, your 3.1 program probably won't be able to use them. I'm not sure if the later versions of LabVIEW can use the old hardware drivers either. If the data processing that you need to do is with text or binary files created by your old program, then I wouldn't anticipate any problems.

Thanks for that info...

As you suspected, I will not be needing to use or distribute any hardware, DAQ, GPIB or prot driver resources
or drivers.

My app is simply an independent guy that collects CSV-based data files and analyzes the data. The app in no way
needs to interact with the LV3.1 VI that is running and collecting/storing the data.

I have LV6.0...so a LV6.0 exe will run on Win95? What if I was just to install the LV6.0 development
system on the target and run my data proc app as a vi? Could the two apps and VIs coexist and run at the
same time? Would the LV6 install eat-up the existing DAQ/GPIB drivers from the LV3.x install??

Thanks!

Installing the 6.0 development should be okay. It seems that as long as I've been doing LabVIEW, I've always had at least two different versions installed and sometimes three. Never had a problem except with hardware drivers. If you do a custom install, you then have the option to not install any hardware drivers. Once upon a time, LabVIEW always installed itself in the \Program Files\National Instruments\LabVIEW folder but since 6.0 I believe, it installed in a version specific folder so you shouldn't have to worry about overwriting the old 3.1 folder but I would make a backup to be safe.

Hello –

Just to complement what Dennis mentions, you can run two LabVIEW applications (of different versions) at the same time without any problems.
