    At first sight it seems to be a permission issue.

    Are you administrator on the machine?

    Need an answer? No, you need a question

    I would try uninstalling using any Administrator accounts you have, preferably the one used for the initial install.

    If that doesn't work, you can try deleting the Microsoft SQL Server folder and registry keys, but I'm not sure I trust a server after that.

    I once had a Production Windows 2003 Custer (2 servers) with a broken SQL 2005 instance that could not be repaired, uninstalled or re-installed, even with Microsoft Tech Support remoted in. Unfortunately the answer was to reformat both C: drives and start over with the OS. That was the worst week of my career.
