Need help with Visual Studio 2008 Beta 2 Setup issues ?
The two forums that I would suggest are
for Visual Studio 2008 Install and Setup
for Visual Studio 2008 Express Editions - Installation and Setup
and for VSD Specific functionality or feature issues please continue to use the forums listed under http://forums.microsoft.com/MSDN/default.aspx?ForumGroupID=11&SiteID=1
