Hi,

I have created a client that uses WSE 3.0/MTOM to transfer files to and
from our server to our clients. I know that WSE 3.0 is not supported by
Windows 98 SE but I tried it on one of my clients machines and it works
perfectly. My problem is that I have a test macine at work running
Windows 98 SE as well but it throws an error as soon as I try to create
the service. I created a very simple Web Service (Hello World) and
client to test the problem.
For example it throws the an error when I call:

dim proxy as New helloworld.ServiceWse

The Error I get is:

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.

It doesn't even connect to the Webservice before it throws the error. I
have tried changing the webservice address to all kinds of things but
it always returns this error. Do I need to install something else that
would help this work. When I call the normal webserice it works fine
(dim proxy as New helloworld.Service).

Any help would be greatly appreciated.
