问题
I tried installing xampp from the following site: http://www.apachefriends.org/en/xampp-windows.html
I had problems installing. When the control panel runs, it shows green signal for MySql and Mercury only, and especially when I start Apache, it gives an Exception.
And at some point it says to disable UAC, but I guess that is not recommended in Windows, so what should I do?
And I also received an error which said "class not registered".
The following are the errors I receive when I start Apache:
11:27:40 [Apache] Problem detected!
11:27:40 [Apache] Port 443 in use by "Unable to open process" with PID 1476!
11:27:40 [Apache] Apache WILL NOT start without the configured ports free!
11:27:40 [Apache] You need to uninstall/disable/reconfigure the blocking application
11:27:40 [Apache] or reconfigure Apache and the Control Panel to listen on a different port
11:27:40 [Apache] Attempting to start Apache service...

12:04:53 [Apache] Status change detected: stopped
12:04:53 [Apache] Error: Apache shutdown unexpectedly.
12:04:53 [Apache] This may be due to a blocked port, missing dependencies,
12:04:53 [Apache] improper privileges, a crash, or a shutdown by another method.
12:04:53 [Apache] Press the Logs button to view error logs and check
12:04:53 [Apache] the Windows Event Viewer for more clues
Where are these logs buttons? And from where to free the ports?. I don't use Skype so my port 80 is probably free. Please help.

I was able to fix this by disabling UAC control and restarted it. But then contrary to my expectation after enabling UAC again it is still working fine.
