When trying to use UI verify tool on the HP PC Hardware Diagnostic tool it is throwing error as below, I think there is some issue with the Diagnostic tool it self as we are unable to find that application from UI Verify tool.
See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

	JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (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 computer
rather than be handled by this dialog box.
