# nsShellExecAsUser NSIS Plugin

**Personal modified version**

---

## Original Description

**ShellExecAsUser plug-in**

Execute the specified program using ShellExecute.
Useful when the installer process is running with elevated privileges (UAC) but you want to launch an application as the standard logged-in user (e.g., launching the application after installation).

## Features

- Launches applications as the current desktop user
- Bypasses UAC elevation if the installer is running as Administrator
- Supports standard ShellExecute verbs (open, runas, print, etc.)
- Supports window show modes (SW_SHOWNORMAL, SW_HIDE, etc.)
- Win95/98/ME/NT/2000/XP/Vista/7/8/10/11 support
- NSIS UNICODE support

## Usage

```nsis
ShellExecAsUser::ShellExecAsUser "action" "command" "parameters" "show_mode"
```

**Parameters:**

1. `action` - The verb to use (e.g., "open", "runas", "print"). Can be empty `""` for default action.
2. `command` - Path to the executable or file to open.
3. `parameters` - Command line arguments.
4. `show_mode` - Window display mode.

**Supported Show Modes:**

- `SW_SHOWDEFAULT`
- `SW_SHOWNORMAL` (default)
- `SW_SHOWMAXIMIZED`
- `SW_SHOWMINIMIZED`
- `SW_HIDE`

**Working Directory:**

The plugin uses the current NSIS output directory (`$OUTDIR`) as the working directory for the launched process.

## Example

```nsis
Section "Launch Application"
    SetOutPath "$INSTDIR"
    ShellExecAsUser::ShellExecAsUser "open" "$INSTDIR\MyApp.exe" "" "SW_SHOWNORMAL"
SectionEnd
```

To launch a URL in the default browser as the user:
```nsis
ShellExecAsUser::ShellExecAsUser "open" "https://example.com" "" "SW_SHOWNORMAL"
```

## Include file

There is no wrapper macros file for this plugin. Call the plugin directly as shown in the usage section.
