I would like to also strongly recommend Peter's advice on only using Windows Installer clean up utilities as the very last resort when everything else fails. We've had to rebuild a users Vista SP2 machine recently because he took IT matters into his own inexperienced hands, googled MSICUU.exe & broke his installation of our own software so it no longer uninstalls properly (component reference counts are permanently set to 1, re-installing the app sets them to 2, uninstalling won't remove files & registry entries as the component reference counts are only decremented to 1 with no way of decrementing them to 0).
Also test your packages using Virtualization as Bob A. recommends on his blog & you should catch these issues before you ship your package -> http://www.joyofsetup.com/2007/09/24/test-your-setups-virtually/ On a VM you don't even need to fix the below issue for that installation, just revert the VM back to before you installed, fix your code, build it & try again.

Subject: Re: [WiX-users] Unable to uninstall Cleanup utilities are a last resort because they can leave the machine in a corrupted state. You have a better option: Rebuild your msi *exactly* as before but with the custom action corrected or removed, (or it might be easier to edit it with orca to achieve the same result). Reinstall and recache the new MSI with msiexec /fv and then uninstall the now corrected version.

Subject: Re: [WiX-users] Unable to uninstall Had the same problem recently; http://majorgeeks.com/download.php?det=4459 helped. You will need to manually cleanup program files etc., but this should let you run your (fixed :~) ) installer.

Subject: [WiX-users] Unable to uninstall Hey everyone, I made an installer with 2 custom actions, taking care of rollback as well. The problem is i messed up with one of them during uninstallation, and every time i try to unistall, it fails and the rollback takes place. So i am unable to uninstall (neither from the msi nor the control panel) Any ideas what i can do now?
