AppleScript updater not run on osx86 10.4.10?

[duckpond]

I downloaded a software called JPEG-JFIF Repair, but it requires

AppleScript 1.8 or higher to run.

 

First, I don't know what AppleScript is, and in my Applications

folder, there is AppleScript subfolder, and AppleScript Utility is

there! The version says 1.0, I then downloaded AppleScript 1.8.3

Update from http://docs.info.apple.com/article.html?artnum=120128

 

The downloaded dmg file mounted okay, but when I click on the icon

"Install AppleScript", the prompt says" You can not open the

application "" because it is not supported on this system"

 

Why? because I am not running on a genuine Mac book rather a Dell

Dimension 9100 installed MacosX 10.4.10?

 

Any help?

 

Thanks,
