Hi there,
Was SQL Server 2005 already installed before you tried to install VS 2003? Because you should rather install VS 2003 first, and then SQL 2005.
SQL installs a very basic version of VS2005 for BI purposes (SSAS, SSRS, SSIS), as it is the only way to develop these types of projects in SQL 2005. You can't open C# Proj or VB Proj files with it, (you can't even open DB projects for some unknown/insane (take your pick
) reason). You'll need to install the full version of VS 2005 to get this functionality.
I think you'll have to format the machine and then install VS2003 first, and then SQL 2005. When I did BI contracting work, we used SSRS 2000 and 2005. When we set up the dev machines we installed everything in this order: VS2003, SQL 2000, SQL Reporting Services 2000, Service Packs, SQL2005, Service Packs, VS 2005 (if needed.). Otherwise, we couldn't do anything.
To cut a long story short, I think the existing VS2005 used by SQL, stuffed up the installation somehow of VS2003. The only solution I know of is to format the machine and try again by installing everything in the correct order.
The Question is the Answer, and the Answer is the Question!
