Registry Repair Appilcation

We are seeking to add to our portfolio a high end registry optimization application that is error and bug free. Ideally we are looking for a white label developed and tested application that can be adapted to our own GUI as developing a program from scratch has too many issues to work out. The app we are looking for will be fully current for use with Windows 7 - and have a proven track record of performance. It must be completely free of any traces of adware or code that triggers any anti-virus or spyware warnings. The program must be accurate and does not generate any false positives. The program will features a free scan component - and then a paid upgrade version. Ideally - the provider will be able to modify the download structure / format to our needs and be able to customize which features are available in the free version vs the paid version. If you are able to combine a anti/spyware element to the program - you definitely would get our business. Please only bid if you have a working prototype we can test as we are not interested in developing a product from scratch.
