VisualVM - not supported JVM

Hi,
when I start monitoring any application, on Monitor tab, instead of CPU graph, there is message: "not supported for this JVM"
on Sampler tab: under Summary:
CPU sampling: Not available. Failed to create JMX connection to target application.....
Memory sampling: Not available. Cannot connect to target application. Make sure the application is running on a supported JDK 6 or JDK 7.

there are a few strange things:
1. this happens on every application that I am trying to profile - except VisualVM itself.... profiling VisualVM is fine and works well
2. (maybe this could be the problem) when I look at About in VisualVM it says "System: Windows 7 (6.1) , x86 32bit"
but in fact I am running 64bit JDK on 64bit OS (win7)
here is java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)
could you pls advise me what to do or where is the problem?
thanks a lot
