Can I customize the controls?
Yes, absolutely. All EMX controls offer extensive options to customize both appearance and behavior to match your specific requirements.
Do you have a trial version?
Yes. Eremex provides a free, fully functional 60-day trial version of the EMX Controls library so you can evaluate the product within your own projects. The trial version includes all the features of the commercial version but will display a trial notification message during use.
What does the license include?
The license grants you the right to create new applications, as well as receive updates and technical support for one year. Applications created during your active license term will continue to function normally with no restrictions after the license expires.

After expiration, you must not update the EMX Controls library version or change the project names in those existing projects. Doing so will cause EMX Controls to display a trial version message.
Do I need a license for each developer?
Yes, our licensing is per-developer. Each developer who works with the EMX Controls library requires an individual license.
What if a developer has 2 computers?
One license can be activated up to three times. Because the license is hardware-bound, a developer can activate it on multiple computers or save the remaining activations for future hardware configuration changes (such as replacing a hard drive).
Can I develop or make changes to a project after the license expires?
Yes, you can make changes to the project after the license expires, with the exception of updating the library version or changing the project name. Please note the following details for expired licenses:

- If you keep the same library version and project name, the rebuilt application will work normally with no license messages.
- If you change the library version or project name, the rebuilt application will display a trial version message.
- During debugging, the trial version message will always appear without an active license, because debugging is part of the development process and requires a valid developer license.
Do I need an additional license to build a project in CI?
No. Licenses are only required for active development. Because continuous integration (CI) environments only build the project rather than develop code, they do not require an additional license.
Can I develop applications using a remote connection with RDP?
Yes, but standard licenses have limitations over RDP. When developing via a remote connection, the license manager cannot create the required license file, causing the application to display a trial message. If your workflow requires remote development, please contact us to request a license type without these restrictions.
Is there a free non-commercial license for open-source projects?

Yes. To support open-source development, we offer free non-commercial licenses. If you are the author of an open-source project and wish to use our library within it, you can apply for a license using the following service:

For more details on eligibility requirements, see Free Non-commercial Licenses for Open-Source Projects.

Is there a free student license?
We do not currently offer a dedicated license for students or educational institutions, but you can apply for our free non-commercial license if your academic work is part of an open-source project. Otherwise, you are welcome to use our free 60-day trial version to evaluate the EMX Controls library. This is twice as long as the standard 30-day trial offered by most component vendors, giving you ample time for your studies.
Do you have real-world examples of using the Controls Library?
Yes. Prominent real-world examples of the EMX Controls library in action include the cross-platform version of Delta Design CAD and the SimPCB Lite CAE software. Their graphical user interfaces are largely powered by our controls.
How do you plan to develop the EMX Controls library?
We are constantly taking into account the feedback from our customers. Regular updates to the EMX Controls library include important fixes and new features based on your requests.
