Cannot remove SQL Server 2012 I was in the process of installing SQL Server 2012 x64 Express Management Studio and encountered one heck of an issue.

I was most of the way through the installation process when my computer locked up and I had to do a hard restart. 

Now, the computer seems to think that I have components of SQL Server 2012 installed when in reality I do not.

I tried going to the control panel and removing the components but most of the way through the removal process I get the following error:


  "Microsoft SQL Server 2012 Service Pack 1 Setup
  
  The following error has occurred:
  
  SQL Server Setup has encountered an error when running a Windows Installer file.

I've spent a couple hours on several days looking around for a fix to this but I haven't been able to locate a solution as of yet.
I managed to resolve the issue. I wasn't able to uninstall SQL Server but I downloaded an installer, converted it to a .zip and extracted it and then pointed the setup to that as the install media. Doing this I was able to get Management Studio up and running.

Thanks for all the suggestions!
