How to convert win 95 LV 4.0.1 application to LV 8.0 (Developer Pro Edition) on win xp pro

[lvsupport06]

How do I convert multiple windows 95 Labview Executable applications written in LabView version 4.0.1 and convert it to be a native LabView 8.0 application running on windows XP? When trying to open this exe file in version 8.0 it gives me an error. I'm new to LabView and wondering the most practical and simple way to convert this application into a version 8.0 app. I also have LabView version 4.0.1 for win NT installed in a different folder. Thanks.

You have an executable written in LabVIEW 4.01 and you want to convert the executable to a LabVIEW 8.0 executable? The short and quick answer is you can't. The only way to do the conversion is to have the original source code. An executable does not contain the diagram. The diagram is the "source code" for LabVIEW and the diagram is required to load an older version into a newer version of LabVIEW. What you're trying to do is sort of like trying to open Excel.exe and get the original C program out of it.

You cannot open an exe file in LabVIEW, just as you cannot in in C or any other compiled language.

If you have somewhere the source of this program in llb or .vi format it should open directly in lv8.

the source format is still readable in version 8 but version 4 cannot read higher versions

lvsupport,

(kinda weird name when taking into account your Q)
I am afraid this will probably not work out very easy, as there have been _some_ changes in LabVIEWs operation mode introduced during the years. So there are chances that you need to fix something during that update process.
LabVIEW usually opens and converts VIs from up to 2 versions back and can save VIs for one major version backwards. So you need someone with at least LV6 to open, convert and save your code (to mass-compile it). If you have access to this version this would be the easiest solution. Otherwise you need a volunteer to perform this action and you need to trust that person - (s)he gets _your_ code!
I still have a PC with an installed LV6, but it is 6.02 German, which would possibly introduce extra problems. So maybe there are others...

I heard of an update tool (maybe on info-labVIEW, search on SearchVIEW.org), but cannot remember if this was just imagined or if it really exists.

Just my € 0.02!
