Uninstall DirSync fails with "Administrator privileges are required to run installer. Please re-launch installer with administrator privileges."

There seems to be a bug with uninstaller of Mcrosoft Forfront Identity Manager Synchronization Service). Even if running "run as administrator" the uninstaller stops with the error message:

Administrator privileges are required to run installer. Please re-launch installer with administrator privileges.

 Steps to solve

1. Find the uninstall string from registry
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{C9139DEA-F758-4177-8E0F-AA5B09628136}
2. Open a "run as administrator" command prompt
3. Run the command in registry string "UninstallString"
4. Click "Remove"
