************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

DEMO1 is for sim, are you a subscriber? If yes, enter your license code.

I am not a subscriber yet and was using Demo1 for license on sim only but it does not let me use it anymore and ask me to do license as light. It onli gives me the sim accnt option. I will become a subscriber in a little less than two weeks...

Light Edition is the simulation only version. Is this not what you wanted?
