Apache Friends Support Forum

Good morning/evening everybody,

I am trying to install XAMPP on my Windows10 system.
but Apache won't start as port 80 in use by "unable to open process" with PID4
(NT kernel & system) apparently a new 'legal holdup' by MS?

Following some advice, I tried port 8080 (in 3 places: httpd.conf > listen, httpd.conf > servername and in control panel > config > services and port settings) but this blocks Tomcat.

Which port should I use in the three locations and what other changes should I bring to make thigs work smoothly?

Thanks

Do you really need Tomcat?

a free one. ports up to 1024 are privileged, so don't use this one. Commonly ports with high numbers (32000 - 65000) are free.
