unable to create file:
Registry backup will continue, but no restore information for the ERDNT program will be saved. This means that later restoration of the registry can only be done manually, by using another OS to copy back the files.
In fact it is clear that nothing is saved. Clicking O.K. produces the next message.
Error saving file
continue with next file?
[RegCreateKeyEx:5 - Access is denied]
And so on through the remainder of the files.
