CRM Install is stuck

I am trying to install MSCRM 2013 on a test server. It has been installed and uninstalled several times on this server. It is now stuck at "Microsoft SQL Server Reporting Services" in the Systems Checks. The last entry in the log is 13:12:37|   Info| UrlAccessValidator linking to help topic: html/01f421a9-da60-4d47-a06a-75550ee94430.htm

And it just sits there, no error and no movement.
