Not able to run second instance of XAMPP on Windows

Postby serten » 30. January 2017 18:41

Hi, I am trying to run two instances of XAMPP on Windows 10. Each instance has different version of PHP. I installed second XAMPP next to the first one, changed ports from 80 to 8080 and 443 to 444 and ran it. When I ran it for the first time, there was no problem, it ran good. But when I changed vhosts and restarted Apache server few times, it happend that I cannot run it again. Always I get this error message:

Code: Select all
14:40:31  [Apache]  Error: Apache shutdown unexpectedly.
14:40:31  [Apache]  This may be due to a blocked port, missing dependencies,
14:40:31  [Apache]  improper privileges, a crash, or a shutdown by another method.

14:40:31  [Apache]  If you need more help, copy and post this

Skype is not running, all ports checked with netstat and no application is using ports 8080 or 444. First instance of XAMPP on ports 80 and 443 is running correctly. And it doesn't matter if I run it together or separately.

Do you have any idea how can I fix it? Thanks for help
