SQL Server - Windows Installer Service Error (Error Code 1601)

Sometimes, you get this error when installing SQL Server 2005. Following is what has fixed the issue for me:

  • Go to windows services (Start->Run->services.msc) and start Windows Installer service if it is not already started.
  • If you are not able to start Windows Installer service, run msiexec /regserver command from command prompt.
