I am trying to uninstall iprint because it doesn't work with vista.
Whenever I try to uninstall iprint it gives me this error:

Setup has detected that you have not restarted your machine since
installing/uninstalling the iPrint client. You must first restart your
machine to finalize the previous install/uninstall before you can continue.

I have rebooted multiple times and it still gives me the same error. I
cannot print until I get iprint uninstalled. Please Help!
