If after running Registry Booster scan and fix, one of your applications stops working, your application might have a conflicting registry entry which Registry Booster is identifying as invalid.
In order to restore your previous functionality we suggest that you click on the 'Restore' tab from the Registry Booster interface menu. Select the earliest restore point and restore it. This will restore your computer to that particular date and time.
We periodically release new builds to address conflicts with third party software. It is important to make sure that you are using the current latest version of Registry Booster. For more details please check the following page:
