我的C＃程序在其他计算机上导致APPCRASH

Question

I wrote a program with .Net 4.0 in C#, and it works well in the two computers in which I compiled it. But when I copy the program into other's computers, the program even didn't show it's UI, and gives out a MessageBox like this:

The box says my program has cause an APPCRASH. Anyone has any idea how to fix the problem?

Answer 1

Could be several reasons. One of the more common ones is that you're compiling it for a .NET framework that the target machine does not have. Another could be that you're compiling for 64-bit, while target machines are 32-bit.

Some of the steps to fix this:

If you're using Visual Studio, right click on your project and go to Properties . In Application tab check to see which Target framework is being listed. It could be .NET Framework 4.5.1.
Change it to .NET Framework 4 Client Profile and see if it runs on your target machines. Also, under Build check to see which Platform target options you have selected and adjust accordingly. It might be helpful to select x86 rather than Any CPU.

Other thoughts/tips:

From the screenshot, it appears that you're running it on Windows 7 machines, so I doubt that .NET framework is the issue; in that case, ensure that target machines contain all the appropriate libraries that you're using. If you have some non-native libraries, make sure that you set Copy Local to true for them.

By the way... when you say you copy it, I'm assuming you're copying all the appropriate files along with the executable, right? There might be some files, such as libraries, app configuration files, etc., that you need to copy along with it.

David Khaykin mentioned the fact that you might have an unhandled exception there. Therefore, as suggested in this SO thread , you may want to implement an event handler for the AppDomain.CurrentDomain.UnhandldedException event and check the value of the e.ExceptionObject.ToString() .

Here's MSDN link to help you with that (scroll to the bottom to see an example): http://msdn.microsoft.com/en-us/library/system.appdomain.unhandledexception(v=vs.110).aspx

Some ways to analyze crashes:

Here's a neat article that describes how to analyze your crashes:

It uses AdPlus, which you can read more about and obtain at http://support.microsoft.com/kb/286350

Here's a more direct link to WinDbg debugging tool: http://msdn.microsoft.com/en-us/windows/hardware/hh852365 (scroll down halfway and make sure you get the Windows 7 version if that's your OS).

Those are just some of the things that I've done over the course of my C# adventuring, so hopefully one of them can help you.

我曾经遇到此问题（ APPCRASH引用kernelbase.dll ），在我的情况下，由于用户配置文件损坏（没有确定的原因，但我之前遇到过几次蓝屏），我遇到了一个问题，这阻止了一些（但不是全部） ！）我的应用程序突然无法使用：要进行验证，请在故障计算机上尝试创建新的Windows用户，将应用程序复制过来并尝试执行。

I checked the event log in my target machine, and foud some useful information. The information is just next to the "APPCRASH" one, and it says like "can't find a file...". Then I checked my program and found a lib haven't been copied there by the compiler.

It seems the event log can really help.

Thank you all who cared!
