I’m trying to setup an enviroment to develop in SharePoint.
I have XP with Visual Studio 2008 Profesional, on XP I have a virtual Windows Server 2003 where I install Share Point Services 3.0.
On XP I want to install Visual Studio Extensions for Windows Sharepoint Services 1.3, I have already modified the registry like http://fernandof.wordpress.com/2008/02/11/how-to-install-the-sharepoint-2007-vs-2005-extensions-on-a-workstation/ mention.
But when I try to run the set up I received the following error 
I google for this error and found that I must install it using the msiexec /i option, but the error continues.
My question is can I install this on an xp machine?
XP isn’t supported.

You’ll have to setup a VM to do SharePoint development on XP.
Now if you’re adventurous you can try this:

I’d recommend a server 2003/2008 VM for SharePoint development though.
