Windows Service CreateProcessAsUser不运行某些可执行文件 [英] Windows Service CreateProcessAsUser don't run some of the executables

问题描述

我已经在.net中编写了Windows服务来调用可执行文件.

执行.net可执行文件(如silverlight安装程序)时没有问题.

但是，当我尝试对其他可执行文件(例如winrar安装程序)执行相同操作时，在CreateProcessAsUser()方法上抛出异常.

方法调用是这个

I have written a windows service in .net to call executables.

There is no problem when executing a .net executable like silverlight installer.

But when i try the same thing for another executable like winrar installer an exception is thrown at CreateProcessAsUser() method.

Method call is this

CreateProcessAsUser(m_SessionTokenHandle, m_ApplicationPath, CommandLine, ref l_oSecurityAttributes,ref l_oSecurityAttributes, 0, creationFlags, envBlock, WorkingDirectory,
                    si, pi)

CreationFlags参数设置为CREATE_UNICODE_ENVIRONMENT|DETACHED_PROCESS.

有关于此异常的任何想法吗?

CreationFlags parameter is set as CREATE_UNICODE_ENVIRONMENT|DETACHED_PROCESS.

Is there any idea about this exception?

推荐答案

问题:
-你有什么例外?错误代码可能会给您一些想法.
-您正在处理什么操作系统?请注意，依赖Windows安装程序服务的安装程序在启用UAC的情况下不需要提升的权限，而独立安装程序则需要. 请参阅以下讨论: http: //stackstackflow.com/questions/2426594/starting-a-uac-elevated-process-from-a-non-interactive-service-win32-net-power [

Questions:
- What is the exception you got? Error codes might give you ideas.
- What is the OS, you are dealing with? Be aware, that installers that rely on windows installer service, don''t need elevated rights with UAC enabled, but standalone installers do.
