问题是，我完全搞不清楚到底出了什么问题 ${NSD_GetText} ，因为它总是返回一个空字符串。

我被卡住了

您没有向

${NSD_GetText}

传递有效的窗口句柄，因为您忘记了变量名上的

$

前缀。将

${NSD_GetText}hCtl_configForm_atmCmdIp$T0

更改为

${NSD_GetText}$hCtl_configForm_atmCmdIp$T0

等

Function un.onUninstSuccess
.....
FunctionEnd

Function un.onInit
....
FunctionEnd

Section uninstall
