Hi,

Installing EPiServer 5 R2 on Windows XP latest SP, I have .NET 3.0 + 3.5 installed, asking for it to install in to the default SQL Server 2005 Developer Edition I get:

System.InvalidOperationException: The installation failed, and the rollback has been performed. ---> System.ApplicationException: Process C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regsql.exe exited with errorcode 1:

* As an aside looks like this site is broken too, trying to cut and paste the error text in to here popped up a window with a 404 on page: http://world.episerver.com/Util/tinyMCE/jscripts/tiny_mce/plugins/paste/pastetext.htm, using Ctrl-V - thank goodness right-click -> Paste worked *
