Game Launcher Creator V3

AOPS2 – Patch Settings

The AOPS2 Patch settings dialog allows you to configure your patching system inside the launcher. Some options may not be available for all Editions.

The Indie version cannot embed the patching system directly into the launcher page. It will display as a popup window which is customizable. If you wish to embed the patching system directly into your launcher page/design, you must upgrade to Developer edition. Developer Edition also unlocks many more features too.
General Settings
Window Title

Specify the Window Title to display for the patcher.

Window Size

Specify the size of the patch window in pixels (Width x Height).

Silent Patch (Developer Only)

Allows for a silent patch process. If you are using your own custom page in the launcher for the patching, you must enable this. You must also send the /S1 commandline in the action where you run the AOPS2 patcher.

Exit Launcher

Instruct the patching system to Exit the game launcher when the patching process starts. For obvious reasons, you should not uncheck this if you are embedding the patching system directly in your launcher page.

General Setup
Online Directory

This must be the full, absolute URL to the online folder where your latest patch files are stored (example: This folder must be accessible for the patching system so you may need to set permissions correctly.

Online Patch File

This must be the full, absolute URL to the online patch list file. This file must be accessible publicly. You can test this by typing this URL into your web browser and seeing if the patch list shows (or downloads). (example:

Online Salt

This must be the full, absolute URL to the online salt file. This contains your hash salt. You must not use # or | characters inside your patch salt. (Example:

Custom Extension

You must specify the custom extension you wish to use for your patch files. This can be absolutely anything you want, although we recommend keeping it to something that has never been used before (or GLC is fine).

The reason why we append a custom extension to the end of your files is because there are major issues serverside and clientside using the standard file extensions. Many servers will not permit the upload or download of files like .exe, .zip etc. and many personal computers will not permit the downloading of .exe, .zip files etc. External software can cause issues.

By using a custom extension, most of this can be avoided, resulting in a flawless patch system.

Compression (Developer Only)

Here you must specify the compression ratio to use for your latest game patch files. This uses LZMA2 compression. The range is 0 – 9 with 0 being no compression and 9 being the highest form of compression.

We cannot guarantee compression will work with every single project (or file). This is because LZMA compression can sometimes have a hard time with particular files, mostly system files. In our tests, it has worked around 95% of the time. We did notice some oddities with some system files, in particular dll files that couldn’t be compressed.

You MUST make sure the files are not in use by the operating system or another application. This too, can throw errors as the file must not be in use in order to be compressed.

Splash Screen
Splash Enabled

You can toggle whether the splash screen is enabled or not.

Download Splash

You can toggle this to ON to tell the patcher to download your splash screen from your webserver (formats supported: JPG, PNG, BMP). You must specify the full, absolute URL to this (example:

Show in Silent Patch

Even if you are running a silent patcher, you can still choose to display your splash screen to the user.

Splash Timer

You must specify in frames, how long to display the splash for. 60 = 1 second, 120 = 2 seconds. Seconds are in increments of 60. For 1 minute, use 3600.

Base Installer

You can choose to assign a Base Installer to your patch setup, should certain conditions be met. A base installer is a good option if the user runs the launcher for example, and it appears your game isn’t installed or something is missing. You can then choose to download your base installer and then run it, so the initial installer can be run for your game.

For example, below, you can choose to instruct the patcher to check the registry to see if a particular entry exists. If it doesn’t, it will download the base installer.

Require Base

Toggle this to ON, if you require the base installer option.

Base URL

The full, absolute URL to the base installer on your webserver (example:

Reg Root

The Root Registry Key for a base install check

Reg Current

The current key for the base install check

Reg String

The string entry to look for in the registry key for the base install check

64-Bit Key

Toggle this to ON if you are using 64-bit registry keys, or the user is using 64-bit. Most of the time, you should turn this to on, unless you know your users are only running 32-bit machines (very unlikely).

Require Pre-Exec

Require base installer if one of the pre-execs fails.

Base Pre-Exec


Restart Patcher

Restart the patcher after the base installer has downloaded and finished running. This allows your patching system to run immediately after they have installed the base installer.

Version Base

Require base installer if local version information is missing or incomplete.
