This type of error means the file has either been removed or corrupted. First, run antivirus software. Check the recycle bin to see if the file was moved there by mistake. If so, restore it to where it used to be. Then try rebooting the computer. If that doesn't solve the problem, try reinstalling the program that advrcntr5.dll came with, Nero CD/DVD burner. Also update any device drivers that might be using the file.
