SQL 2008 R2 Setup-I get Could not open key: UNKNOWN\Components\C89F41A0CA86...


  • I am trying to install SQL 2008 R2 on a Windows Server 2008 machine. It has had SQL 2005 and 2008 R2 installed before.
    I uninstalled everything to do with SQL using the Add/Remove Programs, CCleaner and Windows Installer Cleaner.
    I am running SQLEXPRWT_x64_ENU.exe (Signing time of Monday, April 05, 2010 9:29:28 AM) that I downloaded from Microsoft. I Unblocked the file, I am logged in as Administrator and I Run as Administrator.
    I get
