按鈕插件在 MUI NSIS 安裝程序中不能用於多個按鈕

Question

在 GetButtonID function 中，當給出多個按鈕事件處理程序時，它會在顯示目錄 MUI 頁面對話框之前自動退出。 但是，當只給出一個按鈕事件處理程序時，目錄頁面顯示沒有任何問題。

!include "MUI2.nsh"

!define IDC_BUTTON_CDRIVEPATH 1200
!define IDC_BUTTON_DDRIVEPATH 1201

!define MUI_PAGE_CUSTOMFUNCTION_SHOW GetButtonID **    <---in this function only one button event handler works, if two handlers are given , then installer crashes**

Function **CDRIVEPATH**
   MessageBox MB_OK|MB_ICONEXCLAMATION "The Software will be installed in : C Drive"
FunctionEnd

Function **DDRIVEPATH**
   MessageBox MB_OK|MB_ICONEXCLAMATION "The Software will be installed in : D Drive"
FunctionEnd
;--------------------------------

Function **GetButtonID** 

GetFunctionAddress $R2 CDRIVEPATH 
ButtonEvent::AddEventHandler ${IDC_BUTTON_CDRIVEPATH} $R2 

;when this second button handler is given ,then installer autoexits as soon as it has to show the Directory MUI Page dialog:

GetFunctionAddress $R3 DDRIVEPATH 
ButtonEvent::AddEventHandler ${IDC_BUTTON_DDRIVEPATH} $R3

FunctionEnd

此行為是由 ButtonEvent.dll 插件中的錯誤引起的。 獲取這個插件的新版本來解決它。
