Bytessence Install Maker

Bytessence Install Maker is a freeware sofware installer targeted at individual developers or small companies who need to package their software products for distribution without paying hundreds of dollars on other installation platforms.

BIM helps you create installers without wasting your time with scripting or or other complicated installation mechanisms, however it is still flexible enough to offer advanced tasks or component management. The projects can be built and compiled from a multi-language, straight-forward interface.

The installers generated by BIM can run programs, modify the registry, create shortcuts and internet links, register DLLs, add environment variables, install fonts and many others. In addition, the uninstaller module is able to automatically reverse all the changes to the user's PC.

New! Bytessence Install Maker video tutorial

A video tutorial for Bytessence Install Maker has been released to help new users learn the basics. It covers some of the important features of BIM: creating shortcuts, defining components or running the program at the end of the installation process. You can see the tutorial on this page.

Download BIM

You can download BIM from the links below. If you would like to use BIM from a memory stick or similar device, it's recommended to download the portable version, otherwise you'll most probably find the installer version more convenient. Please make sure to uninstall older versions before installing the current release to avoid any conflicts. To check the integrity of the downloaded files you can use our freeware MD5 calculator available here.

* = This translation covers only the installer and uninstaller part of the program. The main program will remain in English (or any other language for which BIM has a translation).

If you wish to contribute with language files you can translate one of the files from the Localization folder of your BIM installation (please see the FAQ section for more information). If you don't have time to translate the whole program, you could try to translate only the installer language file (~160 lines long).

Frequently asked questions

Q: How to translate BIM?
A: To localize BIM you can open the file called 'English.ini' from the 'Localization\Installer' directory (for the installer) or the 'Localization\Main' directory (for the main program) of your BIM installation and translate the lines. The files use the standard INI layout so you can use any raw text editor for translation (like Notepad). To make the job easy you can use IniTranslator, an open-source translation utility. After you finish, save the file with ANSI encoding (using the proper codepage). If you want to share it with other users you can send it in an archive at the support e-mail (see the contact page) and it will be published here.
Q: How to install translations?
A: To install translations, unpack the archive to a temporary location (like the Desktop) and copy the extracted .INI file(s) to the 'Localization\Installer' directory or the 'Localization\Main' directory of your BIM installation (for example 'C:\Program Files\Bytessence Install Maker\Localization\'). After copying the file, restart the program if it was running then open the Settings dialog. At this time you should be able to see the name of the installed file in the translations box. To activate it, click the desired language in the list and press 'Accept' to save the settings.
Q: How do i create shortcuts on the desktop?
A: To create a desktop shortcut, go to the Advanced tasks section, enter a name for the task (e.g. Desktop shortcut), select 'Create shortcut' from the task type drop-down box then click the 'Add' button. In the Shortcut output field type <Desktop>\MyProgram (replace MyProgram with the desired name). The rest of the fields can be filled just like in the help file. To see what locations are available for usage within BIM, see the Using BIM - Adding tasks - Path variables topic in the help file.
Q: What compression does BIM use?
A: The current version of BIM uses ZIP compression (via Zlib) because of its speed, reliability and popularity and BLP compression - a custom file format based on the LZMA algorithm for its excellent compression ratio. It is possible that in the future BIM will offer support for other formats as the program now uses an extendable plugin architecture.
Q: Does BIM support runtime packers like UPX?
A: Yes, BIM supports external exectutable packers. It's recommended to use them from BIM's user interface so they will be executed before the compressed data is inserted in the executable. You can add the desired exe packer by going to the Settings dialog - Exe packer section. We recommend using UPX for 32-bit installers and MPress for 64-bit installers. Please see the help file for more information on how to enable external compression.
Q: Why aren't other image formats supported for the installer logos?
A: For the moment only .bmp images are supported because the overhead of the bmp loader is very small compared to others like PNG (which adds an extra 100 kb to the installer module). At the same time the bmp files used by the module are compressed when creating the installers so their size will be much smaller in the final distribution.
