So, you generated the file using the 8.0 version of the utility, and then you started seeing errors in LoadLocalizedPanel when you run your program. Is that correct?
If so, and based on Bilal's earlier reply, you want to make sure that you are also using the 8.0 version of LoadLocalizedPanel. This function is implemented in the localui.fp instrument driver that you are including in your project. Can you verify the full path of that file, to see if it is inside your CVI 6.0 or your CVI 8.0 installation? (To view full path names in 8.0, just right-click on the project tree and select the appropriate option).
If you loaded the 6.0 project directly in 8.0, it should have automatically updated the path of that file to make it be relative to 8.0 instead. If that didn't happen for some reason, I would be surprised, but at least that would explain your error. In any case, if that is what happened, you can easily fix it by replacing the 6.0 version of localui.fp with the 8.0 version. You do this by right-clicking on the file's name in the project tree and selecting "Replace File in Project". You should do this instead of changing the version of the .lwl file, which we don't recommend.
