I'm trying to install SQL Server 2012 with SP1 on a laptop with Windows 7, but I'm getting an error immediately upon clicking setup.exe. Unfortunately, it's not a very helpful error message:
I've checked the prerequisites - I have .NET Framework v4 and v3.5, and Windows Powershell v2 installed. I currently have SQL 2008 R2. I've tried stopping all of the SQL services, but that didn't make any difference. Any ideas what I should look at next?
