Apache does not start

[vmetnev]

I installed XAMPP on my computer. I previously had installations of mssql and filezilla on my computer, so I skipped these two items when I was installing XAMPP. The problem now is that when I go to XAMPP control panel I can not use it to start mysql and FileZilla. Is it possible to connect previously installed mysql and FileZilla to newly installed XAMPP?

Are you sure, "mssql" (instead of MySQL)??

Is it possible to connect previously installed mysql and FileZilla to newly installed XAMPP?

Xampp is no software, it is only a name for a distribution of a couple of software products. If you already have an MySQL(?) Installation running, you simply may use this installation instead of that, which comes with Xampp. There is no action required.

Same for filezilla.
