InstallShield2015制作安装包----------卸载前结束执行中的进程

方法一：InstallShiel直接调用cmd命令来杀掉进程。　　　　

     //更新或卸载时先关闭应用程序
     sCmdLine=" /c taskkill /f /im \"Frs.exe\"";
     nResult=LaunchAppAndWait("cmd",sCmdLine ,LAAW_OPTION_HIDDEN|LAAW_OPTION_NOWAIT);

备注：

　　1、命令行前 ，记得加上   /c

　　2、LaunchAppAndWait()函数第一个参数“cmd”，还有另外一种方式。并不是很好用。

 STRING scCmd;
 STRING sCmdLine;

 scCmd=WINDIR ^ "system32" ^ "cmd.exe";
 nResult=LaunchAppAndWait(scCmd,sCmdLine ,LAAW_OPTION_HIDDEN|LAAW_OPTION_NOWAIT);

方法二：来自网友写的一些代码。

 //              When an array is created in InstallScript, a VARIANT variable

 //              to a _VARIANT pointer so that the _SAFEARRAY pointer can be
 //              extracted. The pointer to the actual data is then extracted
 //              from the _SAFEARRAY pointer.
 //
 // Parameters:  structArray - Array variable.
 //
 // Returns:     POINTER - Pointer to array.

调用方式如下：

    if ProcessRunning("Frs") then
        MessageBox("Application \"Frs\" is running,will been killed ", INFORMATION);
        ProcessEnd("Frs");
    endif;
