LabView 7.1 and Win 98

[Marce]

Hello,

I don't think this ir the right place for this question but since I'm kind of despaired, I must try any possible assistance.

I'm quite new to LabView, although I've worked very intensively in the last few months. I did some learning with LV 5... until I purchased my own copy of LV 7.1 about two months ago.

My first project, which I developed tentatively in LV 5 and have moved lately to LV 7.1, are going to machines with Win 98. I had asked about the fact that LV 7.1 didn't work with Win 98 and the answer I got was that the tool didn't work but that I should be able to run the EXEs. Yesterday I found out that life is not that easy and my LV 7.1 EXEs don't have a chance to work in Win 98 O.S. and I must deliver them to my client by next week.

After some quick research, I see that I can save my VIs in LV 7.0 format and it looks like I won't loose any functionality. My problem is what to do next. I guess I need the Appl. Builder for LV 7.0 which I don't have because I purchased the 7.1 version. Is there any way to get that version of the Appl. Builder? I still don't haave much experience with N.I.'s approach to this kind of customer problems but since this forum has been so supportive, I thought maybe I can find a solution here, maybe from the N.I. people. In any case, I've also sent a call for help to N.I./Brazil yesterday and so far, I haven't heard any news from them.

So, HELP!!!

Thanks,

Marce

The last version of LabVIEW to support these was 7.0 (which you pointed out).
You should be able to do a "save with options" (save for previous) and build it.
I think this has a very good chance of running on a Win98 box.

Hi,

You mean build it with the Application Builder of LV 7.1?

Yeah this is what I was thinking. If you save it as a previous 7.0 version and build it in 7.1 it should
work as it will be using the (slightly) older 7.0 files.

I'm skeptical that this will work. When you run the app builder, won't it reload the VIs, recompile them and then save them into the exe as 7.1? The app would still require the 7.1 run-time engine engine and I think the installer for the 7.1 run-time will give you an error if you try to run it on win98.

A possible solution might be to post your VIs and ask if someone with 7.0 can build an executable for you. Long term, you might want to buy a copy of 7.0 or contract with someone sho does have a copy to do the builds for you.

[Don_Phillips]

I am not really sure, never tested it myself. I just seems like it should work however.
I figured saving as previous 7.0 you would be able to use the 7.0 run time... I have no reliable way to test this (no 98 boxes)

But as soon as you open it with LabVIEW 7.1 and it's app builder, it gets converted to 7.1. I just did a rebuild of a 7.0 VI with 7.1 and created a dll. The new dll requires the 7.1 run-time.

Yes, this can't work! The Application Builder does load the VIs into the development environment and saves them from there to the build application before eventually packing everything in the distribution kit for installation. As such it is recompiled for the palttform and LabVIEW version the Application Builder is running on and also linked with the executable stub of that version so that the compatible runtime system is required.

If you want to install an app which runs with the 7.0 runtime system you need to build it in LabVIEW 7.0.

Thanks Rolf. Far be it for me to disagree with an NI employee ;), but Maelstrom's answer needed to be corrected.

[Marce]

Thank you all. It apparently does not have any solution but to use Appl. Builder 7.0
