Build crash in Windows

Just subscribed to Corona SDK Android on Windows.

Using built 544 and also 505,with any project open in Simulator, with Internet on.

I select File, Build… and it crashes:

Corona Simulator.exe - Application Error
The instruction at “0x003d834c” referenced memory at “0x05dbecb8”.
The memory could not be “read”.

and in the console window it says:

Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object

My environment:

WindowsXP SP3 32 bit
jdk 1.6.0_21
JAVA_HOME is C:\Program Files\Java\jdk1.6.0_21

I also had this same error when using the trial
version of built 505.

I have tried deauthorization, registry delete of Corona key, re-install many times, but always the same error. Am I missing an
important step?

Using Eclipse with Android SDK - no problems.

Hope you can advise. Thanks!

Here’s the snapshot of the error:

PROBLEM SOLVED:

STEP 1:
Uninstall Corona SDK (I’m using Build 505 for Windows).

STEP 2:
I totally removed all traces of JAVA (jdk, updates, jre, everything) using Revo Uninstaller. Then, I re-installed Java JDK1.6.0_21 (the same version I had before the uninstall) from scratch.

STEP 3:
Re-install Corona SDK.

NOTE:
I avoided downloading and installing the latest JDK because it might break my Netbeans and Eclipse, and other Java Apps which I already have on my PC (which had their libraries config set on JDK1.6.0.21)
