Hello,

I am trying to set up an Umbraco website on my local PC. My setup is:

• IIS 7
• Visual Studio project with latest Umbraco CMS from Nuget
• Remote SQL Server (I'm the administrator)

I think I've followed all the required steps, and I am prompted with the installation screen, but it goes wrong once I've given the database information during the installation process.

I don't think there is a problem with my connection string, because I am offered the choice of a starter kit after entering the db info. It's when I choose to install a starter kit that it goes wrong.

Here are the relevant lines from the log file

2016-03-10 21:31:47,976 [P8072/D4/T10] INFO  Umbraco.Web.Install.Controllers.InstallApiController - Executing installation step: DatabaseConfigure

Any ideas?
