53. Why do I get an Error Code 5 when I try to install upgrades or update patches?

The complete error message may be: "An error occurred while trying to replace the existing file: DeleteFile Failed; code 5. Access is Denied".

This is usually because you have the application open when you are trying to install the update. Close the program and try installing the update again. If the application appears to be closed and you are still getting this error, reboot your computer.
