XAMPP on Windows - Attempting to start Apache service... - No Port block

I have installed XAMPP on my windows 7 machine but can't get Apache to work.

After opening the XAMPP panel and installing Apache service: I have tried start it, it always get stuck at "Starting apache service..."

On start I get the following:

7:36:57  [main]     Initializing Modules
7:36:57  [main]     The MySQL module is disabled
7:36:57  [main]     The FileZilla module is disabled
7:36:57  [main]     The Mercury module is disabled
7:36:57  [main]     Starting Check-Timer
7:36:57  [main]     Control Panel Ready
7:37:02  [main]     Executing "services.msc"
7:41:50  [Apache]   Attempting to start Apache service...

Event Viewer:

The Apache service named

reported the following error: >>> httpd.exe: Syntax error on line 172 of C:/xampp/apache/conf/httpd.conf: Cannot load modules/mod_ssl.so into server: The specified module could not be found.

I also get an ERROR for the .NET Runtime Optimization Service:

.NET Runtime Optimization Service (clr_optimization_v2.0.50727_32) - Failed to compile: PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 . Error code = 0x80070002
PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35

On the first start i had some .dll problems but i solved them, I do not know if it is related.

I already tried everything in: "XAMPP - Apache could not start - Attempting to start Apache service" without improvement.

Any advice on how I could resolve this ?

Thanks

Go to Xampp control panel and click on config->httpd.conf then go to line no 171 and change ServerName localhost:80 with ServerName localhost:81 It will work.
