问题描述
在安装之前尝试使用卸载字符串卸载软件(并在InitializeSetup
中使用Exec
运行该软件),它不会等待卸载完成,而是进入Inno中的下一步安装设置.
Trying to uninstall a software using the uninstall string (and running that with Exec
in InitializeSetup
) before installation, it doesn't wait for the un-installation to complete but proceeds to the next step of installation in Inno Setup.
我正在使用以下代码和我试图在Installshield产品中卸载的软件:
I am using the following code and the software I am trying to un-install in an Installshield product:
Exec(
ExpandConstant('{pf}\InstallShield Installation Information\{{XXX8X88X-XX8X-88X8-X8XX-88X888X88888}\setup.exe'),
'-s -runfromtemp -l0x0004 -removeonly -remove', '',
SW_SHOW, ewWaitUntilTerminated, ReturnCode)
推荐答案
setup.exe
最有可能执行实际卸载的子过程并退出.因此,Inno Setup似乎不等待该过程完成.这是一种常见的行为,因为卸载程序需要删除自身,如果它仍在运行,则它无法执行的操作.因此,它会在一个临时文件夹中创建其自身(或另一个可执行文件)的副本,并从该文件夹中(重新)执行.
The setup.exe
most probably executes a subprocess for an actual uninstallation and exits itself. So Inno Setup seemingly does not wait for the process to finish. This is a common behavior, as the uninstaller needs to delete itself, what it cannot do, if it still running. So it creates a copy of itself (or another executable) in a temporary folder and (re)executes from there.
根据 InstallShield文档,您可以尝试添加/w
或/Clone_wait
切换到命令行:
As per InstallShield documentation, you can try adding /w
or /Clone_wait
switches to the command-line:
/Clone_wait
...此参数指示原始设置应等待克隆的安装过程完成,然后退出.
/Clone_wait
... This parameter indicates that the original setup should wait for the cloned setup process to complete before exiting.
