I have 2 'office' Primary Interop assemblies


office v7.0.3300.0 (c:\windows\Microsoft.NET\Framework\v1.1.4322
\office.dll


and

Microsoft Office 11.0 Object Library
c:\windows\assembly\GAC\Office\11.0.0.0__7.......\ office.dll



I have reinstalled Office 2003 and now it works when i start a new
'Excel' project.

But, how can i add manually to an existing 'excel' project the good
assembly ?



Thanks.
