Cannot delete wamp folder? Trying to reinstall (3 replies)

I installed wamp a while ago on my computer and was using it to create php, but one annoying thing that was happening was whenever i'd do an insert in a database, it would insert doubles of everything. So i tried uninstalling wamp to try and reinstall it to see if that would fix the error, but unfortunately after the uninstall, the wamp folder still exists in my C drive with the bin folder and apache within and windows will not let me delete it, and says i need admin privileges even though i am the admin, and when trying to reinstall wamp i get an error because of it saying i need administrator privileges to install. So i even tried using unlocker to delete it but even that wouldnt let me, it seems as if this folder cannot be deleted.
How can i fix this so i can get wamp to reinstall
Thanks in advance
