i realized that i already installed Microsoft Visual C++ 2008 Redistributable Package so i just repaired but it did not solved the problem.
我意识到我已经安装了 Microsoft Visual C++ 2008 Redistributable Package，所以我刚刚修复了它，但它没有解决问题。
then i looked for the configuration and saw that "Generate Manifest" is "No" in Release when it was "Yes" in Debug.
然后我查找配置并看到“生成清单”在“发布”中为“否”，而在调试中为“是”。
so i changed and tried again then it worked.
所以我改变并再次尝试然后它起作用了。
i did not know that this configuration may affect like that, (and i dont remember when i changed it)
我不知道这个配置可能会影响那样，（我不记得我什么时候改变了它）
anyway.. thanks for your other answers...
无论如何......谢谢你的其他答案......

Have you searched your hard disk for the file? You may find it in a directory such as:
您是否在硬盘上搜索过该文件？您可以在以下目录中找到它：
C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT
C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT
If it's there, copy it to your \windows\system32 directory.
如果它在那里，请将其复制到您的 \windows\system32 目录。
Also copy msvcm90.dll and msvcr90.dll while you're at it.
同时复制 msvcm90.dll 和 msvcr90.dll。

Check your project settings. If you're not generating a manifest for your Release build, the DLL will need to be in the System32 directory.
检查您的项目设置。如果您没有为发布版本生成清单，则 DLL 将需要位于 System32 目录中。
Also, if your Release and Debug builds are going to the same directory, it could be seeing the Debug manifest, which would point it to the debug version of the DLL. Your best bet is to generate an embedded manifest for all builds.
此外，如果您的 Release 和 Debug 版本进入同一目录，则可能会看到 Debug 清单，该清单将指向 DLL 的调试版本。最好的办法是为所有构建生成一个嵌入式清单。

You probably turned off manifest embedding in your project in release configuration.
您可能在发布配置中关闭了项目中的清单嵌入。
