Thanks - that makes sense. I'm away for a couple of days but I'll check the VS options when I get back and let you know.

Hi,<br />
<br />
I've got something weird going on with Visual Studio. I have Office 2007 installed as well as both Visual Studio 2005 and Visual Studio 2008. I can develop VSTO solutions for Office 2003 using VS2005 without problem. I can also create a VSTO Word add-in for Word 2003 using VS2008 and .NET 3.5, build it and deploy it without problem. However as soon as I close my Word 2003 add-in solution, when I next try to open it using VS2008, I get the Visual Studio Conversion Wizard popping up saying the solution was created in a different version of Visual Studio (which it was not). If I run the wizard, it changes the add-in project to use VSTO 3 and changes the PIA references to use the 2007 PIAs.<br />
<br />
Any ideas (other than developing it using VS2005 and .NET 2)?<br />
<br />
Pete

VSTO &amp; Visual Studio Versions

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.
