Possible troubleshooting

Resolution and display

• OpenGL technology impact on remote access: Our interfaces are using OpenGL technology. This implies that the remote access using direct rendering is not working with OpenGL. In that case, the OpenGL application sends instructions directly to the local hardware bypassing the target X server. This is only possible with single machine. We cannot use it in MonolixSuite with X11 forwarding. Thus, an indirect rendering should be used, i.e. the remote application sends instructions to the X server which transfers them to the graphics card. It is possible to do that with ssh application, but it needs a dedicated configuration depending on the machine and the operating system. Other application as VNC or Remina can be used for an indirect rendering.
• If the graphical user interface appears with too high or too low resolution, follow these steps:
  • open Monolix
  • load any project from the demos
  • in the menu, go to Settings > Preferences and disable the "High dpi scaling" in the Options.
  • close Monolix
  • restart Monolix

cmd.exe not is path

If you get the following error message: Cannot find cmd.exe in current system path PATH, please follow the steps below to add C:Windowssystem32, which contains the cmd.exe executable, to the PATH.

• from file browser, right click on Computer > Properties. You arrive in control panel > system and security > system.
• click advanced system settings (on the left of the window)
• click environment variables in the pop-up window
• in the system variables, edit the Path variable:

• add  C:Windowssystem32;  at the beginning
• save and retry

Antivirus problem

When downloading the package, or launching the installer, the antivirus may tell that the executable file is risky, considered malicious and stopped working. This is due to the fact that MonolixSuite embeds a compiler for the Mlxtran language. Thus, the antivirus puts it in quarantine or removes it. Two solutions are available:
1/ Deactivate your antivirus auto-protection process during download and installation, or
2/ Restore the file from the quarantine.
