Microsoft (R) .NET Framework Installation utility Version 4.0.30319.1

Exception occurred while initializing the installation:
System.IO.FileLoadException: Could not load file or assembly ‘file:///blablabla\blablabla.exe’ or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515).

解决办法很简单：找到服务的exe，右键属性，unblock，完事。
如果服务还要加载别的dll，那么一个个来吧……
