Can not log on to Apache server

[achoudhury]

I am using windows 8.1 when I try to start Apache from the control panel, it tries but shut down, and I get the following message.

11:17:45 [Apache] Attempting to start Apache app...
11:17:45 [Apache] Status change detected: running
11:17:46 [Apache] Status change detected: stopped

11:17:46 [Apache] This may be due to a blocked port, missing dependencies,

11:17:46 [Apache] the Windows Event Viewer for more clues
11:17:46 [Apache] If you need more help, copy and post this
