Hello, A student in my course (cced here) is trying to open Chimera 1.15 and this is the error message that appears: "chimera exited abnormally; the exit code was -1073741819. Use the --debug command line option for the full error message." We cannot open the program, which mean we cannot get to the command line. Thoughts about how to proceed? We have already removed/uninstalled previous version and re-downloaded new one. The same messages appears each time. Best Cassidy -- Cassidy R.

You don't say which platform this is on. I'm going to assume it's on Microsoft Windows. You can get the debug messages by using the Start menu and opening "UCSF Chimera 1.15 / Chimera - Debug". That said, the typical cause of this problem is an outdated graphics driver. Please update the system to the latest and greatest version. This is especially true right now if you have AMD Radeon graphics, but also applies if you have Intel or NVidia graphics. Regards, Greg On 11/11/2021 8:58 AM, Cassidy Terrell via Chimera-users wrote:

Yes this is for a laptop with Microsoft Windows. How do I update the system? On Thu, Nov 11, 2021 at 2:02 PM Greg Couch <gregc@cgl.ucsf.edu> wrote:

You don't say what kind of graphics you have. Or whether or not you have administrative access to the system. The rest of this assumes you do. If you don't have administrative access, you'll need to get the system administrator to update the system. To find out what graphics you have, right-click on the background and select "Display Settings". Then click on "Advanced display settings". And then click on "Display adapter properties for Display 1". And the Adapter Type will be what you have. Since you have a laptop, first try going to the vendor's support web site and get the latest driver for your system. If you don't have a laptop, or if that doesn't fix the problem, you'll need to go the graphics vendor's website for newer drivers. * for AMD: www.amd.com/drivers * for Intel: downloadcenter.intel.com * for NVidia: www.nvidia.com/drivers Then find the new graphics driver for your system, and install it. Or use the tool the website provides if it has one. Regards, Greg On 11/12/2021 7:42 AM, Cassidy Terrell wrote:
