We have existing VS 2008 VSTO add-ins for Word 2003 and Excel 2003. We are unable to upgrade the Office version at this time.
We have just tried to upgrade our solution to VS 2010 and it converts and compiles fine, but when building and running the add-in we receive a message saying that the required version of Office is not installed.
Is there any way of getting around this issue (without upgrading to Office 2007 or 2010) so that we can use VS 2010 to build this add-in?
These files contain user preference configurations that are in general specific to your machine, so it's better not to put it in SCM. Also, VS will change it almost every time you execute it, so it will always be marked by the SCM as 'changed'. I don't include either, I'm in a project using VS for 2 years and had no problems doing that. The only minor annoyance is that the debug parameters (execution path, deployment target, etc.) are stored in one of those files (don't know which), so if you have a standard for them you won't be able to 'publish' it via SCM for other developers to have the entire development environment 'ready to use'.
You need to put your directory structure in your project directory. And then click "Show All Files" icon in the top of Solution Explorer toolbox. After that, the added directory will be shown up. You will then need to select this directory, right click, and choose "Include in Project."

No, unfortunately it's not possible. VSTO 2010 will not compile solutions designed for Office 2003. It is designed to work with with 2007/2010.
To create solutions for Office 2003 you'll need VSTO 2005 on VS2003 or VSTO 2005 SE / VSTO 2008 on VS2008 (in the case of the later, you can also develop for Office 2007).
