LabVIEW App Builder

[RVallieu]

I successfully built an application and needed to make some corrections to the code and want to do another EXE Build - now I am getting the following error!

What is causing this?

NI_FileType.lvlib Error Copying Files

LabVIEW 2009

Error copying files.
Source: C:\Program Files\National Instruments\LabVIEW 2009\vi.lib\Utility\lvfile.llb\NI_FileType.lvlib
Destination: C:\Projects\S\SuperiorWellServices\20090032\SourceCode\New Shell\NODE\propPORT_I\propPORT_Builds\propPORT_I_EXE\propPORT_I.exe\NI_FileType.lvlib

Invoke Node in AB_Source_Library.lvclass:Copy_SourceItem.vi->AB_Build.lvclass:Copy_Files.vi->AB_Application.lvclass:Copy_Files.vi->AB_EXE.lvclass:Copy_Files.vi->AB_Build.lvclass:Build.vi->AB_Application.lvclass:Build.vi->AB_EXE.lvclass:Build.vi->AB_Engine_Build.vi->AB_Build_Invoke.vi->AB_Build_Invoke.vi.ProxyCaller

Visit the Request Support page at ni.com/ask to learn more about resolving this problem. Use the following information as a reference:

Error 8 occurred at AB_Source_Library.lvclass:Copy_SourceItem.vi -> AB_Build.lvclass:Copy_Files.vi -> AB_Application.lvclass:Copy_Files.vi -> AB_EXE.lvclass:Copy_Files.vi -> AB_Build.lvclass:Build.vi -> AB_Application.lvclass:Build.vi -> AB_EXE.lvclass:Build.vi -> AB_Engine_Build.vi -> AB_Build_Invoke.vi -> AB_Build_Invoke.vi.ProxyCaller

Possible reason(s):

LabVIEW:  File permission error. You do not have the correct permissions for the file.
=========================
NI-488:  DMA hardware error detected.

I have this error before and did see a KB article that talks of something similar:

Why do I get "Error 8 Occurred at Open File" When Writing to or Reading From a File?

Try to build after closing all files on your machine. I would also recommend restarting the computer. It seems like this is an intermittent error that shows up during application build.

Or another trick is to specify the builder to place your code in a short path (eg. c:\bld), With the new layout LabVIEW quite easily runs into the 256 character length for a path.

I was just about to post - after the 5th time I shut down LV completely and restarted it the build is working again....
