Maybe you need to use another version of InstallUtil.exe:

c:\Windows\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe
c:\Windows\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe
c:\Windows\Microsoft.NET\Framework64\v2.0.50727\InstallUtil.exe
c:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe

Try to use x64 version from Framework64 subfolder.

不过还是推荐sc delete serviceName进行删除

How to retrieve the LoaderException property?

try
{
  // load the assembly or type
}
catch (Exception ex)
{
  if (ex is System.Reflection.ReflectionTypeLoadException)
  {
    var typeLoadException = ex as ReflectionTypeLoadException;
    var loaderExceptions  = typeLoadException.LoaderExceptions;
  }
}
