一个说简单有点简单，说难有点难得问题。但需要你得帮助。

Question

if (File.Exists(System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory() + "InstallUtil.exe "))
{
if (File.Exists(iname + "gaswsh.exe"))
{
File.Copy(iname + "gaswsh.exe",System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory() + "gaswsh.exe",true);
File.Copy(iname + "gaswsh.exe.config",System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory() + "gaswsh.exe.config",true);
File.Copy(iname + "Genesis.ApplicationService.DLL",System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory() + "Genesis.ApplicationService.DLL",true); System.Threading.Thread.Sleep(1000);
Process.Start(System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory() + "InstallUtil.exe ",System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory() + "gaswsh.exe");
System.Threading.Thread.Sleep(10000);
}
else
{
MessageBox.Show(iname + "\\gaswsh.exe" + " Can not exit !");
}
}

Answer 1

Process.Start(System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory() + "InstallUtil.exe ",System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory() + "gaswsh.exe");
实际上问题就再这里：
如果我把System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory() + "gaswsh.exe"修改为系统的安装路径（一般都是再C:\Program Files下，），就回出错误。
