MATLAB: Do I get a registry error when running getdatasources or opening the Visual Query Builder on Windows

Why do I get one of the following errors when I open the Visual Query Builder on Windows platforms or run getdatasources?

Registry editing has been disabled by your Administrator

Can not export c:\temp\ODBC.INI: Error opening the file. There may be a disk or file system error.

Best Answer

If you see the error

Registry editing has been disabled by your Administrator
the problem is benign. The easiest solution is to click *OK*. You should be able to continue working without further problems.

If that does not work, or you are using getdatasources in a MATLAB file, or you want to address the problem for future sessions, please contact MathWorks Technical Support for further assistance.

MATLAB: Close (all) Variable Editor windows

This closes all docked and undocked ArrayEditors:

desktop = com.mathworks.mde.desk.MLDesktop.getInstance;
Titles  = desktop.getClientTitles;
for k = 1:numel(Titles)
   Client = desktop.getClient(Titles(k));     
   if ~isempty(Client) & ...
      strcmp(char(Client.getClass.getName), 'com.mathworks.mde.array.ArrayEditor')
      Client.close();
   end
end

MATLAB: Does the SYSTEM command not find an existing Windows registry key in MATLAB (R2011b)

Since we are unable to reproduce the issue on our end, we suggest the following:

1. If "ProductId" is available in your registry, the MATLAB command WINQUERYREG will return it. For example, on my machine:

>> winqueryreg('HKEY_LOCAL_MACHINE', 'SOFTWARE\Microsoft\Windows NT\CurrentVersion', 'ProductID')
ans =
00392-918-5000002-85980

Make sure there is a space between Windows and NT.

2. If (1) fails, you can try the following .NET code in MATLAB to check the registry entries:

>> NET.addAssembly('mscorlib');
>> root = Microsoft.Win32.Registry.LocalMachine;
>> root.OpenSubKey('SOFTWARE\Microsoft\Windows
NT\CurrentVersion').GetValue('ProductId')
ans = 
00392-918-5000002-85980

3. If neither works, try the same code from a VB app or a C# app on the problem machine.

4. If that still does not work, the issue is with the machine setup, and your best bet would be to contact your system administrator or Microsoft.
