On this last wizard page, you have to confirm the deletion or modification of registry keys, and choose a backup file name. You may browse the file system for the folder where you want to save the backup file. The backup files are of Registry Editor 5.00 format and can help you later to restore the modified registry keys to initial state. See the How to restore modified entries topic.
By default the checkbox Save the undo file (RegEdit format) is checked. Enter the full path and file name to the edit field. An example is: "C:\ProgramData\RFA_Backups\2001_04_27.reg". It is possible to use the Browse button to locate a path and file name as well. By default the program offers to save the backup file into the "ProgramData" folder.
If you do not want to save a backup of the registry entries then clear the Save the undo file (RegEdit format) checkbox.
To apply changes to the registry, press the Fix Errors button. If the operation is successful, you will receive an information message. Then you can go back to the found registry entries page where you can select other entries for correction if desired, or click Close.
