自定义操作配置如下:

Custom Action Name: MyCustomAction

VBScript Filename: <PathVar01>\MyFolder\MyVBSfile.vbs

ScriptFunction: MyFunction

Return Processing: Synchronous (Check exit code)

In-Script Execution: Immediate Execution

它通过以下 InstallScript 代码执行:

result = MsiDoAction(ISMSI_HANDLE,"MyCustomAction");

当安装程序到达 InstallScript 中的那一行时，安装程​​序会显示错误警报，说明:

"Error 1720.There is a problem with this Windows Installer package. A script required for this install to complete could not be run. Contact your support personnel or package vendor."

MsiDoAction返回的结果码是'1603'，according to winerror.h , 是:

//
// MessageId: ERROR_INSTALL_FAILURE
//
// MessageText:
//
//  Fatal error during installation.
//
#define ERROR_INSTALL_FAILURE            1603L

为什么会这样？我开始怀疑该文件是否包含正确。然而，我指向了正确的文件，并且我尝试通过 InstallShield 支持文件包含 VBS，认为这将确保该文件存在于安装程序中，但结果相同。

最佳答案

在启用日志记录的情况下运行设置揭示了问题:

Action 13:29:19: MyCustomAction.
Action start 13:29:19: MyCustomAction.

Error 1720.There is a problem with this Windows Installer package. A script required for this install to complete could not be run. Contact your support personnel or package vendor. Custom action MyCustomAction script error -2146827278, Microsoft VBScript compilation error: Expected identifier Line 163, Column 37,
blnExample,)

在启用日志记录的情况下运行设置:

"C:\SetupFolder\setup.exe" /V"/l*v c:\Install.log"

This forum thread很有帮助。
