There’s a file called “ccekrnl.dat” in the CCE folder and I cannot delete it. I even tried third party programs, nothing happens. It just says that the file is open in another program when i try to do it myself. How can I delete that file, I thought CCE wasnt supposed to be running all the time. Help please.
Reboot in safe mode. Locate the file and delete it. - I’m sure you already know how.
