Sometime you get garbage when you try to view the fantastico installer. Some garbage error which might look like:
ÜÒ,
.Ž,
..áÒ,imagesóèÒ,includesëÒ, languagesÕ, installer.phpÕ, styles.cssòâÒ,„info.phpýó
1) First thing you need to do is to see if PHP is compiled properly and can interpret other PHP pages, and also check to make very sure that .php is listed as a PHP MIME type (it should be, by default).

2) Then next step is to logg into your server as root via SSH and run the following command:
/scripts/makecpphp
This will fix your issue.
