Hi...all
I've encountered a serious problem while trying to run a vb.net application in the client machine.
My client has the .Net Framework installed.Infact my set up file is already installed in the client machine and i'm still able to execute some part of the application.But when i try to run some other parts of it,it shows some error like this,

"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 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."

Please help me ....I'm already getting fed up with this error.
Thanks.

Were you using some activex controls in you VB application. I'm not sure but it seems you are using Flex Grid control in your application and this control is not registered on target machine.
Either manually register all the components on the target machine or write this functionality in the setup.
