• One software license is required per developer. The developer may install and use the software on a single computer (the main computer you use at work) and is also permitted to install it a second time on a portable computer (your laptop) and to install it a third time on a home computer, provided that the developer is the only or exclusive user of the software product. Please see the Licensing Examples below.
• Run-time deployment of the add-ins created using this product are royalty free. All Add-in Express products are run-time deployment royalty free.

Licensing Examples

• Example 1: A single developer using the software may install it at work on his/her desktop, on his/her laptop and on his/her home computer and only needs to buy one (1) single license, provided that they are the only user of the software product.
• Example 2: A team of 3 developers wish to use the software on 3 computers. The 3 developers need to buy three (3) separate licenses for the software product.
• Example 3: A team of 3 developers wish to use the software on 3 computers and also create builds on a separate build server machine. The 3 developers need to buy three (3) separate licenses for the software product. However, if no development is performed on the build machine and its sole purpose is to generate actual builds of your software, then you do not need to purchase a separate license for the build server machine. If however a developer uses the build server machine for development and this developer does not have a current or valid license to the software product, then you must buy an additional license for the software product.
