Every time i run a nortons fix it comes up with a problem saying "country selection ppct.exe is an invalid registry value".I have tried to delete this but to no avail, any suggestions would be grateful,also in idiot fashion please as not very technical thanks
OK - first double check in Control Panel both Regional Settings (should show English United Kingdom) and Keyboard settings > language should show "English (British)."
If all this is correct then I would consider uninstalling Norton(?) and then if that cures the trouble, decide whether you think it is worth another installation of Norton (fix it?).
On last point, if you only installed Norton in the last day or two, you can often put things back as they were by using scanreg /restore - That will replace the registry at a date you choose going back up to 5 days ago. If you are not sure how to do that- ask here again.
