Hi

I have an automation add-in built using the IDTExtensibility2 interface.
When working with Office 2007 this addin installs and registers without
problems.

With Office 2003 the installation fails - RegAsm returns a message:

RegAsm : error RA0000 : Could not load file or assembly 'Extensibility,
Version=7.0.3300.0, Culture=nuetral, PublicKeyToken=b03f57f11d50a3a' or one
of its dependencies. Strong name validation failed. (Exceptio from HRESULT:
0x8013141A)

My understanding is that the Office 2007 Primary Interop installation
installs Extensibility.dll is in the GAC but that the Office 2003 PIA package
does not.

I have tried simply copying the Extensibility.dll to the install folder for
my project and this does not help.

What is the correct procedure for ensuring that the pre-requisites for an
automation add-in using IDTExtensibility2 are installed for Office 2003?

Thanks for any help

Hi Andrew,

I think you'd better post this question in this group:

What sort of addin is it

It is a COM automation add-in using IDTExtensibility2 as the interface. I
know that some of the technology is shared with VSTO but I thought this was a
different class of application (Tell me if I'm wrong!)

AFAIK all "Com" addins use the IDTExtensibility2 interface. But what
language and application was the addin written in.

Hi Andrew,

Maybe bot, but the NG I pointed you to is visited by people who do Office AND
.NET development, which is a rare combination.
