I cannot start the windows installer service (yes I am the administrator). Every time I right click on a file the windows installer tries to run (it does this twice). I get an error 5 access denied when I try and start the service. The Microsoft web site has a program to clean up the windows installer - this will not run because it requires the window installer. This prevents me from installing programs such as Nero or PartionMagic which try and configure the windows installer.
