A suitable JVM could not be found?

I installed 1.4.1_02 and then I tried install Studio (ffj_ce_win32.exe) and all I get is this error that says : A suitable JVM could not be found. Please run the install again using the option -is:javahome <JAVA HOME DIR>. I tried that too, but I still get the same error. What do I need to do now?

Thanks
