Tomsaw,
My best guess is that somehow the MSXML component that allows us to read the customization file for the user interface library's function panels is not present, or there's a problem with its installation.
Try some of these steps, and let me know what you see:
1. Try doing the same thing in CVI 7.1 and see if you have the same error (this is just for the sake fo curiosity)
2. In 8.0, try running the samples\toolbox\XMLSample.cws example. When it asks you for a file, point it to CVI80\bin\userint.fpc (this is the XML customization file for the UI library). See if you can browse this file's contents using this example program
If you cannot run the example program, then we can conclude that the problem is with the low-level XML component. To do some basic investigation, make sure of the following:
1. Make sure you that the file windows\system32\msxml3.dll exists in your computer
2. In your system registry, make sure that the key
HKEY_CLASSES_ROOT\CLSID\{2933BF90-7B36-11d2-B20E-00C04F983E60}\InProcServer32 also exists, and that its value is
%SystemRoot%\System32\msxml3.dll.
3. If the DLL exists, try to load it yourself from a CVI program (just try to call LoadLibrary on it, and see if that succeeds).
Other than that, I don't have any ideas off the top of my head. Depending on what the results of this are, we might be able to figure out how to proceed further.
