Uninstallation problem!

I want to update to the latest alpha yet when i uninstall it says I have a previous version installed and i need to uninstall it,but i already did.And i found this https://forums.comodo.com/cfp_beta_corner/comodo_uninstallation_cleaner-t9668.0.html

Same problem i have but that cleaner doesn’t fix it,only solution is to do a roll back of the system.so I’m stuck with a old version of alpha.anyone working on this??I have vista32
