How to find my Jrun 4 root folder for MX7.02 server installation

Hi,

I am trying to install Jrun 4 Updater 7 for my ColdFusion MX 7.02 (server installation) setup.  It asked the root folder of my Jrun Installation and I tried a lot of selection but all of them come back with error "The location that you provided does not contain an installation of JRUN 4".  How can I find my Jrun 4 root folder.

Here is the location that I've tried but no luck.   My ColdFusion is installed in cFusionMx7 and I have updated my JVM to 1.4.2_11 and it resides in c:\j2sdk1.4.2_11.

C:\CfusionMx7\runtime\bin

C:\CfusionMx7\runtime\jre

C:\CfusionMx7\runtime\jre\bin

C:\CfusionMx7\runtime\jre\lib

C:\CfusionMx7\runtime\lib

C:\j2sdk1.4.2_11\jre\bin

C:\j2sdk1.4.2_11\jre

C:\j2sdk1.4.2_11\bin

Thanks in advance for any help.
