Umar,
BI 4.1 is NEW release, the vendor will NEVER release a product to support a END OF LIFE products like XP / SQL Server 2005.
Check the Microsoft site for XP End-Of-Life info
http://www.microsoft.com/en-us/windows/enterprise/endofsupport.aspx
You must move your desktop to the lowest supported OS like Windows 7.
Regards,
Ajay
