I had the exact same problem as the original poster however this link given by George from NI didn't solve my problem. Instead I had to follow these instructions to remove the reference to daqmx.rc in the Source Distribution Build.
I Have this error when i try to make an exe :
Error copying files.
Source: C:\Program Files\National Instruments\LabVIEW 8.5\user.lib\LV-LINK\UtilityVIs\nueva.llb\OLGetBoardNames.vi\<GAC>\LvLink2
Librarian Path Location.vi
Visit the Request Support page at ni.com/ask to learn more about resolving this problem. Use the following information as a reference:
Error 1 occurred at AB_Destination.lvclass:Copy_File.vi -> AB_Source.lvclass:Copy_SourceItem.vi -> AB_Build.lvclass:Copy_Files.vi -> AB_Application.lvclass:Copy_Files.vi -> AB_Build.lvclass:Build.vi -> AB_EXE.lvclass:Build.vi -> AB_Engine_Build.vi -> AB_Build_Invoke.vi -> AB_Build_Invoke.vi.ProxyCaller
LabVIEW: An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.
Anyone can help me to solve this item ???? Thanks a lot
