I tried installing the latest version (5.4.1) onto a webserver 2003 box with Sql Express 2005 and dot 2.0.50727  As I need to use the sql server and not a mdf file I will be using the connection string as follows :-
<add name="SiteSqlServer" connectionString="Data Source={SERVER_NAME};Initial Catalog={DATABASE_NAME};Integrated Security=True;User ID={LOGONNAME}" providerName="System.Data.SqlClient" />

The set-up wizard created the database and directory structures fine, but when I come to login I receive 404 the page /login.aspx could not be found?

I tried an earlier version 4.5.3 which is now up and running fine, but am having a few problems with a couple of modules and need to up-grade these.

So. Can webserver 2003 (iis6) with sql express 2005 run version 5.4.1?
If not what is the latest version which supports iis6 with sql 2005?

Thanks
