VSTO: Visual Studio 2005 with Office 2010 64

Question

I was developing a Office 2003 Add-In with Visual Studio 2005. But after unistall Office 2003 and intall Office 2010 x64, my project stops working.

It's present some errors:

Error   7   The type or namespace name 'IRibbonControl' could not be found (are you missing a using directive or an assembly reference?)    x.cs    83  45  x
Error   5   The type or namespace name 'IRibbonUI' could not be found (are you missing a using directive or an assembly reference?) x.cs    358 38  x
Error   3   The type or namespace name 'IRibbonExtensibility' does not exist in the namespace 'Microsoft.Office.Core' (are you missing an assembly reference?)  x.cs    45  43  x

There is some way to make my AddIn run?

Answer 1

Not sure if you have seen this or not, but here's some of the explanations:

Office 2010 32-bit should run VSTO 2005 SE add-ins without modifications, but Office 2010 64-bit will not load VSTO 2005 SE add-ins.

Office solutions that require the Visual Studio 2005 Tools for Office Second Edition Runtime are not compatible with 64-bit versions of Microsoft Office 2010. To run these solutions in the 64-bit edition of Microsoft Office 2010, you must upgrade the project to Visual Studio 2010 or to a Visual Studio 2008 project that targets the 2007 Microsoft Office system.
