J# exe runs on my system but not on others

[Ivan Witteveen]

I have written a windows application in J# using the Microsoft Visual Studio 2005. I have compiled it without warnings or errors and it runs on my system (Windows XP). Users say that it crashes on startup or doesn't start up on their systems, either Vista and XP.

I am looking for someone with the 2005 Visual Studio and Vista who can run the program through the debugger to see what is wrong. It has to be the '05 version of the Visual Studio, because the '08 version doesn't support J# anymore.

It consists of 2 programs A and B. Program A reads some variables from a textfile 1 and uses these to output another textfile 2. Program B is a GUI that allows the user to change values in textfile 1 and run program A.

Who can help me?

Thanks,

Hi,

Welcome to JavaRanch!

Do the users have the .NET framework runtime installed on their machines? It's a separate download, and not everyone has it.

Welcome to JavaRanch. Can't help you myself, but I think the reason the new Visual Studio doesn't support J# is that Microsoft were obliged to withdraw the language from general use.

Of course, that's the nice thing about Java; it will run on any system which supports a JVM with only minimal alterations to the code.

I don't know. Wiki says that the .NET framework is a standard part of Vista. I have the .NET framework version 3.5.

I don't know about Vista, but for XP, it definitely came in an update. Also, Version 3.5 is only about seven months old, so again, a lot of people are likely to not have it yet.

Thanks for pointing this out, because I think this is a part of the problem.

I installed and uninstalled all kinds of versions of the .NET Framework and it turned out that my program only works with .NET version 2.0 or higher. So I assume that Windows XP users who reported that it didn't work, don't have the right .NET version.

This doesn't solve the problem for Vista users, because .NET 3.0 is included in Vista. And the error message they receive mentions an Exception Code: e0434f4d. That is why I think that the debugger could clearify the reason for the crash.
