Deploying VSTO 2005 SE add-in in Office 2010 64bit

Question

Is there any way to install a VSTO 2005 SE Add-in into Office 2010 64bit?

(The solution targets Office Excel 2003, does not use any features of 2007)

If not possible, what exactly would be the limitation?

Thanks.

Answer 1

no, it is not possible. Right now only VSTOR 2010 64 bit can run in 64 bit office 2010.

"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."
