Description

This plug-in allows you to inspect and modify the installer state.

Stack dialog

The stack dialog allows you to view and edit the stack. This is a modal dialog and works the same way as the DumpState_plug-in.

Function .onInit
Push "Stack Test"
Debug::Stack
FunctionEnd

Watcher dialog

The watcher dialog shows a live view of the registers and installer state. This dialog lets you edit registers and state at any time but to avoid crashes you should only do this when the installer is idle.

Function .onInit
Debug::Watcher
FunctionEnd

Command dialog

The command dialog is a WinDbg inspired terminal where you can enter simple commands.

Commands:

• LM - List loaded modules.
• ~ - List threads.
• HWND <HWND> - Display window information.
• q - Attempts to cancel and quit the installer.
• .cls - Clear the output window.
• .echo - Write to the output window.
• .formats <Number> - Display a number in various formats.
• .dvalloc <Bytes> - Allocate bytes in the installer address space.
• d<b|d|p> <Address> - Display byte/dword/pointer at the specified address.

Some of the commands supports the following pseudo-registers: $hWndNSIS, $peb and $pid.

Function .onInit
Debug::Command
FunctionEnd
