hmmm.. I havent tried regcure yet, but registry mechanic have been very helpful to me for 2 years now. Try it out. The installer can be found here: http://www.pctools.com/registry-mechanic/
Note: you have to register it first if you want it to work. It will scan though, but it will not clean unless you register it. Search for it in google. I will not post any license key in here, since it is prohibited.
