You have to delete the file most likely it is named for example oem25.inf. Look in c:\windows\inf and look for the oem file, it is most likely the last one because this is the last driver installed. Open the inf file and see if it is the same one from the bt878 driver you are trying to install. If so, delete that file and the .pnf with the same name.
