DTWAIN Licensing Information

Developer-only Licenses 

The Developer-only license allows you to continue to use and test the DTWAIN Library indefinitely beyond the 30-day trial period but not distribute your applications to third-parties

In addition, a Developer license must be purchased for each developer who works on a product or project using DTWAIN. No matter what type of applications are being developed, a separate DTWAIN Developer License must be purchased for each developer working with DTWAIN.

The Developer License version of DTWAIN will start with a splash screen that will be displayed for 5 seconds when the DTWAIN DLL is loaded in memory, informing the developer and any other person running the DTWAIN application that the DTWAIN DLL that has been loaded in memory is a Developer version.   The splash screen is to ensure that distribution of the Developer version to unwarranted parties is reduced.



To remove the splash screen, a Distribution license must be purchased (see below).   Otherwise, the Developer version is not crippled in any way (no time limits, and no decreased functionality from a Distribution version of DTWAIN), allowing you to continue development and testing of DTWAIN for an indefinite amount of time.

Also, for Developer-only licenses, you are allowed "personal use" of your DTWAIN applications.  If you are using DTWAIN to create applications that you will personally use and/or will not distribute your programs to other companies for others to use, and you do not distribute the DTWAIN DLL and related files, this is considered a valid use of the Developer-only license.  In other words, "personal use" applications do not need any additional Distribution Licenses.

For example, if you create an application that you personally use to scan images, and then on site at another company you use the same program but do not give ownership of the program to the company and the DTWAIN DLL's and other related components are not available to the company when your program is not in use, then you do not need any additional licenses. This still counts as "personal use" of DTWAIN.


Distribution Licenses

Distributing your DTWAIN applications

In addition to the Developer License described above, If you plan on distributing your DTWAIN applications under one or more of the following scenarios:

then you must purchase at least one of the various Distribution Licenses described below, in addition to at least one Developer license.  Otherwise,

A Distribution License grants you the rights to distribute your application to any number of individuals, and with exception of the Toolkit License, royalty-free, for an unlimited number of applications.  On purchase of a Distribution License, the opening splash-screen that comes with Developer-only versions of DTWAIN will be removed.

Distribution Licenses come in the following categories:

The Company Distribution license allows you to create an unlimited number of royalty-free applications that use DTWAIN, and distribute these programs within the same company at a single company site to any number of individuals. If the program will be used on a network, then a Company Distribution license is required. If the application will be used within an Intranet environment, a Company Distribution license must be purchased.

The General Distribution license allows you to create an unlimited number of applications that use DTWAIN, and distribute the programs in any environment and by any means, royalty-free.  The applications can be fee-based, where the user must pay a fee to use the applications (for example, commercial and shareware applications), or freeware applications.   Also, if the application is an Internet based application, then a General Distribution license must be purchased.

The Toolkit Distribution license is a special license required if your application is a programmer's toolkit or API that will allow programmers to call, either directly or indirectly, DTWAIN functions. Unlike the other Distribution Licenses, the Toolkit Distribution License is subject to royalty fees, where the fee depends on your product's pricing and number of projected sales.
