Help with client!

Yea i downloaded client again and again
Re-installed java
re-boot cpu
But i still get an error when opening client. The console comes up so i maximise it nad it says
RuyukScape Client ~~ Loading
'java' is not recognized as an internal or external command,
operable program or batch file.
Press any key to continue . . .

after that it just closes.
what am i doing wrong?

What you using? XP, Vista, or Windows 7? If your using Vista or Windows 7, right click the Client.exe, not the .bat file, and choose run as administrator.

Try deleting your file you have.
Then Install it again and make sure u extract all files to like desktop.
Should work.

In my file at the very bottom there is run and run client. When i clicked run as admin. with run client i get
