Thanks for contacting National Instruments. The most often cause of that error is that you may have that file open in some other application and are trying to access it in multiple locations. I have attached a link below that is to one of our public Knowledgebase articles that talks about this error. Please take a look at this and let me know what you find if you still have problems. Thanks!
In case you check back, how would I know if LabVIEW is accessing the japanese SPT-errors.txt file while I am building my application? Please note, this problem occurs when BUILDING the application from the Project Explorer. At the time I build, I am not running anything else (not even other windows applications).
Like mentioned earlier, there is most likely an application on the internet that you can find and use where you can see what processes are calling specific files or folders to see if that specific file is being used by anything else. It doesn't sound like this is the root of your problem, but it couldn't hurt to check. Also, I have seen a similar problem to this with someone who was using the software Subversion and Tortoise with their application. I am not familiar with this software in particular, but I have attached a link below that goes through the steps that this other person took to try and fix the same error when having this software on their computer. Let me know if any of this helps!
I am not running either of those programs.
The error message clearly states that the problem is that the application builder cannot access the NI Signal Processing Toolkit Error Code Definition file (SPT-errors.txt) which is not being used by any other application that I can find.
I have tried a few things and found this problem to be more extensive than I thought. If I change the supported run-time languages in the build properties to only English and enable the copy error codes option, I get the same error, but with the "Internet Toolkit-errors.txt" file under the ..\LabVIEW 8.5\project\errors\ folder. The root cause of my problems seems to be the copy error codes option in the application builder cannot get access to these files, or at least it thinks that to be the case. Is it possible there was some corruption to my ..\LabVIEW 8.5\project\errors\ folder? This project was originally created by LabVIEW 8.2.1. Could the conversion have done something to cause this problem? Should I try creating a new project and re-creating my currnet build options?
