Error: Apache shutdown unexpectedly.

[ugremfx]

I just downloaded XAMPP and I got this message when trying to start Apache:

6:20:22 PM [Apache] Error: Apache shutdown unexpectedly.
6:20:22 PM [Apache] This may be due to a blocked port, missing dependencies,
6:20:22 PM [Apache] improper privileges, a crash, or a shutdown by another method.
6:20:22 PM [Apache] Press the Logs button to view error logs and check
6:20:22 PM [Apache] the Windows Event Viewer for more clues
6:20:22 PM [Apache] If you need more help, copy and post this

Can anyone help me?

Thanks
