SpreadsheetGear 2010 attempts to register the WorkbookView and FormulaBar controls with Visual Studio 2005, Visual Studio 2008 and / or Visual Studio 2010 during installation. The Express versions of Visual Studio do not support the APIs used by SpreadsheetGear 2010 for this registration, so you must manually register the WorkbookView and FormulaBar controls.

To manually add the WorkbookView and FormulaBar controls to Visual Studio:

1. Install Microsoft Visual C# 2005 / 2008 / 2010 Express Edition or Microsoft Visual Basic 2005 / 2008 / 2010 Express Edition.
2. Install SpreadsheetGear 2010.
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 for earlier versions of Visual Studio or Windows Forms Application for later versions.
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.
10. Name the Tab (such as "SpreadsheetGear 2010")
11. Right-click within the Tab and click Choose Items….
12. Scroll through the list and check FormulaBar and WorkbookView.
