1. 提交阶段，使用vbs调用mysql-connector-net-6.6.5.msi报错

vbs 脚本如下：

Dim ret
Set WshShell = WScript.CreateObject("WScript.Shell") 
ret = WshShell.Run("msiexec /i mysql-connector-net-6.6.5.msi") 

解决方案：

打开 %temp% 目录，查看文件名以msi开头.log结尾的安装错误日志文件（随机名称，如MSIeb1c8.LOG） ...win7默认就会生成该文件，xp下据说需要设置点击打开链接

然后把上述代码WScript.CreateObject....的WScript删掉

Dim ret
Set WshShell = CreateObject("WScript.Shell") 
ret = WshShell.Run("msiexec /i mysql-connector-net-6.6.5.msi") 

2. 安装项目中的生成或提交阶段 执行以下vbs， wshShell.Run strCmd死活执行不成功...原因可能是虽然install.exe和mysql-connector-net-6.6.5.msi文件已经拷贝到安装目录了，但是这种状态还未提交，因此脚本还是找不到这两个文件

     Dim wshShell,strPath, strPathTarget, strCmd, fso
     'On error resume next
     Set wshShell = CreateObject("Wscript.Shell")
     Set fso = CreateObject("Scripting.FileSystemObject")
     strPath = Session.Property("CustomActionData") &"install.exe"  (install.exe即msiexec.exe)
     strPathTarget = Session.Property("CustomActionData") &"mysql-connector-net-6.6.5.msi"
     '这几个引号那是相当烦，就是把整个语句包在一对引号中
     strCmd = """"& strPath &" /i "& strPathTarget &""""  
     msgbox strCmd
     wshShell.Run strCmd
    ‘如果脚本改以下，文件路径存在，则安装包安装成功。
     wshShell.Run "E:\workstation\install.exe /i E:\workstation\mysql-connector-net-6.6.5.msi"

3. 变通的方法，把mysql-connector-net-6.6.5.msi拷贝到setup.exe/安装包目录下，就不打包到安装包里面了，用户执行安装包时，通过OriginalDataBase获取安装包路径，从而找出mysql-connector的绝对路径，然后执行之，WIN7下测试通过

     Dim wshShell,strSetupMsiPath, strDir, strExecPath, strExecTarget, strCmd, fso
     'On error resume next
     Set wshShell = CreateObject("Wscript.Shell")
     Set fso = CreateObject("Scripting.FileSystemObject")
	 'CustomActionData is [OriginalDatabase]
     strSetupMsiPath = Session.Property("CustomActionData") 
	 strDir = GetDir(strSetupMsiPath, "MealBookerSetup.msi")
	 
	 strExecPath = strDir &"install.exe"	
	 strExecTarget = strDir &"mysql-connector-net-6.6.5.msi"
	 strCmd =  strExecPath &" /i "& strExecTarget (strCmd本身就是string，故代码段2中这部分也是有问题的，应把两边的双引号去掉)
	 msgbox strCmd
	 wshShell.Run strCmd
     'wshShell.Run "msiexec.exe /i D:\Program Files\MealBooker\mysql-connector-net-6.6.5.msi"
   

     Private Function GetDir(fullpath, filename)
        dim pos
		pos = 0
		pos = instr(fullpath, filename)
		if pos>0 then
		    GetDir = left(fullpath, pos - 1)
		else
		    GetDir = ""
		end if
     End Function
