Need help to get executable running

Question

Firstly I'm not a programmer and do not pretend to be one. I just enjoy killing some spare time!

I've been usining Visual Basic (started with VS2005 and now onto VS2010) to develop a program. Up until now I've been happy to plod along running the progam from the development environment. However, I recently was asked by an colleague if they could have a copy of the program to use.

Therefore I opted to create an executable file for him to use. The problem is that whislt the executable file runs fine on my machine  (Win 7) where VS2010 is installed, it does not deploy correctly on his machine (XP pro). Following is the message that I get:

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.

 

I've tried inserting an Import System.Windows.Forms into each form, but this has net fixed the issue.

As I mentioned, I'm not a programmer and am at a total loss as to what it all means and how I can overcome this problem.

I would appreciate any help that anyone could offer.

Answer 1

Does the target XP machine have .NET Framework 4.0 installed?

 

Answer 2

Hi Dan

the most common reason I see on the Forums for an app to run on 1 computer with Vista/7 and not another with XP is the build of the app.

see this thread for a discussion:

don't know if it will solve your problem or not, but worth a shot
