Tutorial: How to Create a Portable Application with NSIS

NSIS (Nullsoft Scriptable Install System) is a powerful and versatile tool that allows you to create custom installers, uninstallers, and launchers for your applications. But did you know that you can also use NSIS to create portable applications that can run from any removable media without installation

In this tutorial, we will show you how to create a portable application with NSIS using a simple example. We will assume that you have some basic knowledge of NSIS scripting and that you have already installed NSIS on your system. If not, you can download NSIS from here and follow the installation instructions.

What is a Portable Application

A portable application is an application that can run from any removable media (such as a USB flash drive, CD-ROM, or external hard drive) without requiring installation on the host system. This means that you can carry your application with you and use it on any compatible computer without leaving any traces behind.

Some advantages of portable applications are:

They are convenient and easy to use. You just plug in your media and run your application.

They are secure and private. You don't have to worry about leaving any personal data or settings on the host system.

They are compatible and flexible. You can use them on any system that meets the minimum requirements of your application.

Some disadvantages of portable applications are:

They may not work properly on some systems due to security restrictions or incompatible libraries.

They may not be able to access some system resources or features that require installation or registry entries.

They may not be able to update themselves automatically or receive patches or fixes from the developer.

How to Create a Portable Application with NSIS

To create a portable application with NSIS, you need to follow these steps:

Create a folder for your portable application and copy all the files and folders that your application needs to run into it. For example, if your application is called MyApp.exe and it requires some DLLs and data files, copy them all into the same folder.

Create a NSIS script file (with the extension .nsi) in the same folder as your application files. This file will contain the instructions for creating the portable launcher for your application.

Write the NSIS script using the following template:

```nsis

; Name of the script file

Name \"Portable MyApp\"

; Output file name

OutFile \"Portable MyApp.exe\"

; Request execution level for Windows Vista or higher

RequestExecutionLevel user

; Define variables for the application name and path

!define APP_NAME \"MyApp\"

!define APP_PATH \"$EXEDIR\\${APP_NAME}.exe\"

; Define a function to check if the application is running from a removable media

Function IsPortable

; Get the drive letter of the current directory

GetFullPathName $0 $EXEDIR

StrCpy $0 $0 1

; Get the drive type of the drive letter

DriveGetType $1 $0

; Compare the drive type with \"removable\"

StrCmp $1 \"removable\" +3

; If not removable, show an error message and exit

MessageBox MB_OKMB_ICONSTOP \"This application can only run from a removable media.\"

Quit

FunctionEnd

; Define a function to launch the application

Function LaunchApp

; Check if the application file exists

IfFileExists ${APP_PATH} +3

; If exists, execute it

Exec ${APP_PATH}

; Exit the launcher

Quit

; If not exists, show an error message and exit

MessageBox MB_OKMB_ICONSTOP \"The application file ${APP_NAME}.exe could not be found.\"

Quit

FunctionEnd

; Define a section for the main code

Section

; Call the IsPortable function to check if running from a removable media

Call IsPortable

; Call the LaunchApp function a474f39169
