Installing Kylix as root has the advantage of allowing all users to access the Kylix installation, provided you install it into a "shared" location. I reccomend installing Kylix as root into the directory /usr/local/kylix. However, if you are going to be the only user using Kylix, you may want to install it as that user into your home directory. 

To install as root, type su from the command prompt and enter the super user password. Then, run the Kylix installer. 

Примечание от Vit: обычно при установке от имени root возникает ошибка -10
