安装C#项目未完成

我有一个C#项目，我想为此制作一个安装文件。当我按照构建步骤构建.exe文件时，Visual studio 10中的输出文本显示：

    ------ Starting pre-build validation for project 'Setup1' ------ 
------ Pre-build validation for project 'Setup1' completed ------
------ Build started: Project: Setup1, Configuration: Debug ------

Packaging file 'vattu.mdf'...
Packaging file 'QuanLyVatTu.exe'...
========== Build: 1 succeeded or up-to-date, 0 failed, 0 skipped ==========

当我运行.exe文件（生成后）时，它无法成功加载。

我寻找这个问题，但仍然没有解决。有人能告诉我如何解决这个问题吗。

只需安装“Microsoft.NET Framework 4（x86和x64）”，就像错误所说的那样。

答案就在输出中-安装Windows Installer 4.5和.NET 4…有时错误消息会很有帮助。我下载并安装了.NETFramework4（x86和x64），但Visual仍然显示错误
