Hello @Romthalas !

Commonly, it can be done via the next steps:

1) If you have already installed XAMPP in the C disk , it will have the folder with the path like C:\xampp\htdocs .

2) Create the directory like the una name within this folder.

3) Upload and unzip the UNA package right to this directory. So the path to the index.php file of UNA will look like C:\xampp\htdocs\una\index.php .

4) Open in your browser the URL like localhost/una/ and follow the appearing instructions according to this manual:
