This topic is covered in the online training material (embedded in a 45-minute video) and we keep getting this question, so I figure it’ll help the community to use these quick steps rather than searching through the video. A typical scenario is that you want to debug, edit and debug one or two specific runtimes without having to rebuild the whole OEM configuration. This example is for native (C++) code but the same applies to managed (.NET) code. First, compile the ARX runtime that you have configured in your OEM project: ![image](https://us1.discourse-cdn.com/flex020/uploads/techsoft3d/original/2X/8/830347e7670554188095dae732cfcd1f999ec042.png) ![image](https://us1.discourse-cdn.com/flex020/uploads/techsoft3d/original/2X/3/335faf8c0a70008dd95741602adc85874ad14dab.png) Then, choose **ARX modules only** for binding, build and launch the OEM application from the MakeWizard: ![image](https://us1.discourse-cdn.com/flex020/uploads/techsoft3d/original/2X/4/49c3dc7a976d19830cea42d8e48a5ac9ed51d447.png) Set a breakpoint: ![image](https://us1.discourse-cdn.com/flex020/uploads/techsoft3d/original/2X/f/f5d117ae9db1dacad70f26d4c328b4362f5d4cf4.png) In VS, select ‘Debug’-\>’Attach to process’ (choose your OEM application) - make sure you target ‘Native’ code: ![image](https://us1.discourse-cdn.com/flex020/uploads/techsoft3d/original/2X/5/5c52d7dba43faae37ede0e0748c718eed675872a.png) Run the command… Debug: ![image](https://us1.discourse-cdn.com/flex020/uploads/techsoft3d/original/2X/9/9168197d81444d58def05a35184ead7e967f16b5.png) I also have ‘Attach’ set to ‘Yes’ in my debugging configuration: ![image](https://us1.discourse-cdn.com/flex020/uploads/techsoft3d/original/2X/f/fd5d0bfea71484dc5fc5a31199943301cff2f3fc.png)
