SpreadsheetGear 2009 attempts to register the WorkbookView and FormulaBar controls with Visual Studio 2005 and / or Visual Studio 2008 during installation. The Express versions of Visual Studio do not support the APIs used by SpreadsheetGear 2009 for this registration, so you must manually register the WorkbookView and FormulaBar controls.

2. Install SpreadsheetGear 2009.
3. Launch Visual C# Express or Visual Basic Express.
4. On the File menu click New Project…. The New Project dialog box appears. (You may also Open an existing Windows Application project.)
5. Under Templates, choose Windows Application.
6. Change the Name as desired.
7. Click OK to create the project
8. On the View menu click Toolbox. The Toolbox appears.
9. Right-click in the Toolbox and click Add Tab. A new Tab appears to be named.
