Exception occurred while initializing the installation

小渣渣

Exception occurred while initializing the installation:
System.BadImageFormatException: Could not load file or assembly 'file:///C:\MyPr
ojects\ProxyService\ProxyInstaller\bin\Debug\ProxyInstaller.exe' or one of its d
ependencies. This assembly is built by a runtime newer than the currently loaded
runtime and cannot be loaded..

我用命令行安装Windows服务，出现以上错误：

我安装的过程如下：

1。运行--〉cmd：打开cmd命令框

2。在命令行里定位到InstallUtil.exe所在的位置

InstallUtil.exe 默认的安装位置是在C:/Windows/Microsoft.NET/Framework/v2.0.50727里面，所以你要在cmd里通过cd定位到该位置（cd C:/Windows/Microsoft.NET/Framework/v2.0.50727）

3。操作命令：

1). 安装服务命令：在命令行里输入下面的命令：

InstallUtil.exe  Path/WinServiceName.exe

其中Path表示ServiceName.exe所在的位置，回车即可

安装失败的原因是：我服务是用.net 4.0写的，不能用.net 2.0的InstallUtil去安装服务，所以，应该用C:\Windows\Microsoft.NET\Framework\v4.0.30319文件夹下的InstallUtil去安装服务。

Not that way round, no. The .NET 4 CLR can load .NET 2 assemblies (usually - there are a few exceptions for mixed-mode assemblies, IIRC), but not vice versa.

You'll either have to upgrade the .NET 2 project to .NET 4, or downgrade the .NET 4 project to .NET 3.5 (or earlier).
