The error occurs when you try to install the Add-in Spreadsheet Link EX because of MATLAB not being registered. To work around this issue, please follow the steps below:
1). Shut down all instances of MATLAB and Microsoft Excel.
2) Open a Command Prompt window, and using cd, change to the $MATLABROOT\bin\win32 subdirectory of your MATLAB 7.0 installation directory. (where $MATLABROOT is the MATLAB root directory on your machine, as returned by typing:
at the MATLAB command prompt.). And then, type the following command
3. When MATLAB starts, close it. Using /regserver fixes the registry entries.
4. Close all instances of MATLAB, and install the Spreadsheet Link EX Add-in again.
