Apache server isn't starting on Xampp portable

It may seems as a repeated question but my problem is that I couldn't be able to start Apache server on XAMPP Portable, I'm am aware of the issues that some aplications can cause since they can use the ports where apache is supposed to work, so I decide to change the apache running ports on httpd.conf and httpd-ssl.conf files to Listen on 8080 and 8001 respectively, here are some screenshots of the changes,

http-conf1, http-conf2, httpssl-conf1, httpssl-conf2

In adition to that I also chage the configuration of the "Service & Port Settings" under XAMPP Control Panel, as shown in the folowing image,

xampp-ports

Although, I did all these changes I still can´t get the apache instance running, and keep getting the following error xampp-error, it's important to notice that I´m trying to start apache service in a company workstation and I don't have any admin rights, but I read that ports above 1250 didn't need any admin rigths to run services on them, so I don´t know what to do at this point, any suggestion from you guys would be really appreciated.

Thanks.
