(2) Internet Explorer base libraries are used for web (HTML) editor. See below "Supported Internet Browsers" for application runtime requirements.
(3) For installing or distributing modules.
(4) LocalDB is only supported to create a Knowledge Base, not for use for the generated applications.

Furthermore, the user running GeneXus IDE has to have administrator rights.

Native Mobile(2) * Apple Requirements
* Android Requirements
Angular * Angular requirements

(1) - Apache Tomcat (7.0.67 or higher) is the only servlets server supported for prototyping locally.
Warning: We recommend installing Apache Tomcat from .exe (do not download the .zip option because you could encounter these situations: SAC # 31319)
(2) - Knowledge base Navigator does not support prototyping Offline Apps. Take a look at Offline Native Mobile Applications Requirements.

Execution requirements:

Generator Requirements
.NET * Microsoft .NET Framework 4.6.2(1) or higher
* Internet Information 6.0 or higher (2)
* ADO .NET provider associated with the selected DBMS
* URL Rewrite for REST Services and GeneXus Access Manager (GAM)
.NET Core * Windows: ASP.NET Core Runtime 5.x Hosting Bundle(5)
* Linux: Details...

* Oracle JRE or Open JRE 1.8 or higher
* J2EE Server or Servlet Server(3)
* DBMS JDBC Driver (4)

Native Mobile * Apple Requirements
* Android Requirements
Angular * Angular requirements

(1) - Framework 4.7.2 when SameSite cookie attribute property is set to a value different from 'Do not specify'.
(2) - Internet Information Server 8 when using Server.Socket external object make sure to install the windows feature 'WebSocket Protocol' module in the IIS 8 section.
- Internet Information Server 7 or higher when using Azure.

- Since GeneXus 16 upgrade 4 the Servlets Server requires the support of Servlet 3.0.
(4) - Redistributable JDBC Drivers are included in GeneXus Setup and copied in build time under <Knowledge base Environment Directory>\<Drivers> and referenced in Classpath property.
(5) - The .NET Core Windows Server Hosting Bundle is for running the application on IIS. More information at .NET Core Generator Requirements.


  • To enable the 'WebSocket Protocol' module in Windows follow these steps: "Turn Windows features on or off" -> Internet Information Services ->World Wide Web Services -> Application Development Features -> WebSocket Protocol. It requires restarting the machine
  • To verify that .NET Framework 4.6 is installed, go to "Turn Windows features on or off" and check .Net framework 4.6 Advanced Services

GeneXus IDE on Mac or Linux

Since GeneXus IDE runs on Windows, you need to run it on Virtual Machines with that Operating System and the associated requirements mentioned above when your base OS is Mac OS or Linux.
GeneXus Web will be an alternative to this in the future.
