That's pretty much what the error says: you can't delete the file because it is in use by another program.
The simplest way to solve the problem for an inexperienced user is to reboot the machine, then try to delete the file again. If this does not work, try to reboot in Safe Mode (hit F8 at boot) with the minimum number of services launched.
You can also try to identify the program (from the Task Manager) that's holding the lock and kill it, if you know what you're doing.
