Hi cindym BC,
Please try to uninstall your XAMPP completely:
- stop and unregister all XAMPP related Windows services such as Apache and MySQL
- use the uninstall dialog
- delete the whole xampp directory
After that you should restart your computer, because sometimes ports are not successfully released, especially if you are not acting with enhanced administration rights.
Then, after the restart you should check if your ports 80 and 443 are free (use the
netstat -aon command in your commandline opened as administrator for that)
If this is true, start a new fresh install of XAMPP.
best wishes,
Altrea
