PatchFactory for Windows is a full-featured byte-level patching system for bandwidth-efficient software updating which is sold at a reasonable price comparing to systems of the similar class. PatchFactory provides a robust feature set that gives software developers the ability to tailor the update process to their specific needs.

 

Keeping customers on the most current version optimizes the performance of your product and significantly reduces your end-user support costs.

PatchFactory is a new and innovative software updating and delivery solution, ensuring that end-users always have the latest version of your software. When integrated into your application, PatchFactory performs almost any updating task, including synchronizing files, running an installer, updating your software, and even performing a custom action to keep your customers up-to-date and your technical support calls/inquiries to a minimum.

 

The patch-building engine is an innovative standard for producing version-to-version or cumulative software updates contained in one small, reliable package.

Generated patch packages are small size self-extracting executable update programs in a famous installer style with adjustable user-friendly interface (silent mode is also available). Patches can modify or replace the installed files to add new features, fix bugs, or add new security features.

Unlike setup files, which contain all files needed to run the software, the result update program only contains information concerning modifications (including changes in files/folders structure) made to old version software files relatively to new version files and has an easy-to-use interface with user-friendly dialogs.

 

Using PatchFactory you can create a complete yet compact update installation package for the application and make it available for download, or issue a media that contains the update package. You can also use PatchFactory to keep up-to-date any important data that must be updated very often and which freshness may be critical for your business.

 

The idea behind PatchFactory is simple: when modified file(s) must be transmitted, send only the changes (byte level differences) stored in one reliable self-installing update module rather than the entire software installation package. PatchFactory lossless byte-level compression is not content dependent, so it may be used whenever data is changed at one location and must be efficiently updated and/or archived at another.

 

NOTE: PatchFactory does not deal with any specific data structures, it operates with files as a binary data. Databases or files of other formats can be updated only as binary files (warning: database update can be implemented only if it is not changed on the end-user's machine).

 

Whatever you want to patch, update or upgrade - PatchFactory offers you the most comprehensive, professional, reliable, easy and safe to use, efficient and reasonably priced software update solution. Make your customers always feel up-to-date!
