先决条件可以有两种形式：一种是在安装时从互联网下载，另一种是捆绑到安装包中......对于后者，您必须选择从以下位置下载先决条件与我的应用程序在先决条件对话框中的位置相同...但为了使其工作，您必须将文件作为必备条件下载到您的计算机中...

在您的情况下安装程序for .NET 4缺失所以你得到一个错误，告诉你下载它！

I am Trying to publish my Windows project. But This Error comming.

Error10  To enable 'Download prerequisites from the same location as my application' in the Prerequisites dialog box, you must download file 'DotNetFX40Client\dotNetFx40_Client_x86_x64.exe' for item 'Microsoft .NET Framework 4 Client Profile (x86 and x64)' to your local machine. For more information, see http://go.microsoft.com/fwlink/?LinkId=239883. prjChequePrinting

Please give me a suggision to me.Tell me the process how to publish my windows application.

Prerequisites can come in two form: one is downloading from the internet when installing, and the other is bundled into the installation package...For the later you have to choose 'Download prerequisites from the same location as my application' in the Prerequisites dialog box...But for that to work you must have the files need to be included as prerequisites downloaded to your computer...
In your case the installer for .NET 4 is missing so you got an error that tells you download it!
The missing file can be downloaded from here: http://www.microsoft.com/en-us/download/details.aspx?id=24872[^]
