Error 7 occurred at source does not exist

[yqin]

I have VIs written in LabVIEW 6.1 and works fine. I try to use LabVIEW 7 to build it. But I got error:

********************
Error 7 occurred at source does not exist

Possible reason(s):

LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Mac OS, and / on UNIX.
---
NI-488: Non-existent board.
---
Application Builder: Error copying files.

It does not point out which file is not exsisted? Why?

Hi,

I've had this error message sometimes. I don't know if it is yours but my problem was because I didn't open the VI before trying to build the application.

My advice to your problem is try to open the main VI with LV7. You'll probably have to show LV where are some subVIs. When it is done you can close your main VI and try to build the appication again.

Hope this helps !

I try it. It does not works.

This works ONLY for build .EXE, not for .DLL.

Hello �

From your question, I understand that you are trying to build an executable for LabVIEW 7.0 of some VIs that were built in LabVIEW 6.1.

You need to save all the VIs and subVIs that will be contained in the executable (or DLL) in LabVIEW 7.0 first. For this, the only thing you need to do is to open them in LabVIEW 7.0 and re-save them. If you want to keep copies for both versions of LabVIEW, you could even create a different folder for the version 7.0 ones. When re-saving your VIs just go to File >> Save As and browse to the directory you just created.
Then, you will be able to build the executable for LabVIEW 7.0.

Another possible solution to the problem is what is mentioned in this 5F09C86256745006E4494?OpenDocument>Knowledgebase.

I'm sorry but buiding .EXE is the only experience I've got.

I try this. It gives same error.

But I found that when I try to open the main VI with LV7 then close my main VI and try to build the appication again.It works. But ONLY for .exe, not .dll. Also, If I shut down LV7 and restart again again and load top level VI for build, It give me same error.

Hello �

You could try doing a mass compile of the original code. After the mass compile you should be able to rebuild your libraries in LabVIEW 7.0.

It is VERY important that you keep a backup copy of your VIs and libraries before the mass compile, just in case something goes wrong.

Please take a look at the following Knowledgebase.

Hope this helps!

I tried the mass compile. Same error.

Hello �

I just tried it in my computer and I am able to successfully build an EXE and DLL in LabVIEW 7.1 from a VI build in LabVIEW 6.1.

Can you post the VIs you are trying to build into a DLL?
