Why am I getting ""LABVIEW.LIB could not locate "FResDir". With Labview 5.1?

[rwelch]

All,

I am maintaing some old code.  I have SVN (Source control.)  Last time I had to get into the code there was no problem.  Nothing has changed in the code base.  I went to make a few small changes, when I attempted to open the code I get the Fatal Error mentioned in the Subject.  What is the cause?  And how do I get around it? 

I am running LabView 5.1 and 2009 on an XP platform.

Thanks,

Rich

Do you have TestStand? That's the only mention of FResDir that I found. Using a search, of course.

I have Test Executive the predecessor to Test Stand.

FResDir is an exported C API in LabVIEW since version 8.0. Somehow somewhere you installed a LabVIEW component or extension (DLL form) that gets loaded by something in LabVIEW and tries to access that API.

What NI software did you install between the time it worked and when you got this error message?

I think I added the MathScrip RT Module and maybe the service pack f2.  It is a little chaotic here, I am not sure when I last dug into this code.

Most likely you have an unfortunate interaction between your LabVIEW 5.1 installation and the LabVIEW 8.x or 2009 installation that you use the Mathscript RT installation.

There could be a good chance that you can't run LabVIEW 5.1 (and anything before 8.0) anymore on machines where LabVIEW 2009 and maybe Mathscript RT has been installed.

That is what I was afraid of. 😞  Thanks for your help!

Hi,

I just got the same message you got. I created a dll with Labview 2009 and wanted to use it in LabView 7.1. As soon as I load the DLL the message pops up! The idea of this dll is that anyone could use it, even if they have an older version of LabView. If anyone has a solution please tell me!!

Thanks

[rwelch]

Sorry, no I!  I gave up.  I am now developing on two seperate machines.  Good luck!

Regards,

Rich

Do you have the LabVIEW 2009 runtime installed on the pc with 7.1?
