actual installer software for windows

How to package a large application?

If your project (application, game, databases, etc.) is big in size, it is not recommended to package it into a single executable file. Because it can take a very long time to execute this file or even the install may fails with an error message "run out of memory".

So if the size of your application is larger than 100-300 MB, we recommend you to pack your project into a ZIP archive and distribute it with its installer:

--
setup.exe
data.zip
--

To make it, please follow the following steps:
1. Remove from your Actual Installer’s project all source files (on pages ‘Files and Folders’ and ‘Additional Files’).
2. Select from the main menu ‘File - Create Data File…’.
3. Select a source folder of your application.
A free program ‘7-Zip’ will package your application and create a zipped data file (‘data.zip’) in the same folder as setup file.
Also it will add the following entries to your project:
- a file ‘<SetupTempDir>\7za.exe’ on the ‘Installation - Additional Files’ page;
- a command on the ‘System - Commands’ page:

--
Command: <SetupTempDir>\7za.exe
Parameters: x "<CurrentDir>\data.zip" -o"<InstallDir>"
Show: Normal
Timing: After Installation
Wait Until Process Finishes: Yes
--

The above command will execute a file ‘7za.exe’ at the end of installation, and unpack file ‘data.zip’ into program’s installation folder.
4. Select option 'Force Uninstall' on the 'Installation - Uninstallation' page.

That's it.
