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|a|u> <Address> [Count=1] - 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
