我在Windows 10上使用VS2017编译了一个安装项目。它可以在XP上运行吗？

Question

I have created a setup project using Visual Studio 2017 and compiled it on Windows 10. It is written in C# WPF and the target framework is .NET Framework 4 . The target platform is Any CPU .

Now that I have compiled the setup project, I am trying to run the MSI for it on Windows XP. The MSI runs successfully and installs the program, but the program will not open. I am being shown an error message box that says:

MyProgram has encountered a problem and needs to close. We are sorry for the inconvenience.

According to the computer events, a NotSupportedException error is occurring:

Application: MyProgram.exe

Description: The process was terminated due to an unhandled exception.

Does anybody have any suggestions for how to fix this problem? .NET Framework 4.0 is already installed on my Windows XP machine. Is there a setting in VS2017 that I need to change?

Answer 1

The main problem is in Visual Studio target platform, it have to be X86 otherwise it don't work in xp. The others thinks looks ok.
