为Windows XP x86编译程序

Question

I wrote a windows forms application using VS2012 on windows 8 computer (x64) and I want it to run on Windows XP x86. When I try to run the program I get error "... is not a valid windows 32 application." How can i fix it?

Answer 1

• Right Click Project Name on solution Explorer.
• Select Properties
• Select Build Tab
• Select x86 option for Platform target DropDownList
• Save and build the project

Also make sure that you target the .Net Framework Version same as the version present in Testing machine.

If you are building C++ project then try this:

General -> Platform Toolset -> Visual Studio 2012 -> Windows XP (v110_xp)

Answer 2

Its better that you choose the target as Any CPU .

The compiler shall decide how to invoke the program ( x86 or x64 ) when you choose the Any CPU option , also choose the Any CPU platform.

Answer 3

Maybe far away guess with given that less information.

You should change Compile Target to x86 from

Project->Application Properties->Compile 

Set Target CPU to x86

Answer 4

It sounds like you may be experiencing issues related to the Windows XP Targeting for C++ in Visual Studio 2012. Support for Windows XP with C++ targets was added in Visual Studio 2012 Update 1, but must still be explicitly selected in your project properties.

Windows XP Targeting with C++ in Visual Studio 2012

There is a great deal of additional information at the above link, but the specific setting you are looking for in the C++ project properties is General → Platform Toolset → Visual Studio 2012 - Windows XP (v110_xp)
