Maestro fails to start and produces error messages. What can I do?
There are a number of common reasons that Maestro can fail with error messages. The items listed below give you some things you can check to determine the cause of the failure, which is rarely a problem with Maestro itself.
- Check that your graphics card is adequate for running Maestro. If you can start Maestro with the -SGL option, then the problem is likely to be your graphics card or graphics driver. Maestro is an OpenGL application that uses graphics extensively, so if you have a low-end graphics card that does not support OpenGL, you might find that you cannot run Maestro. Some onboard graphics cards are not adequate for running Maestro. If you are running Maestro on a remote server, the server must have an adequate graphics card as well as the local display host.
- Check that you have the latest graphics driver from the manufacture of the graphics card installed. Out-of-date drivers are often the cause of problems running Maestro. If your system has been updated, you might have to reinstall the graphics driver.
- Check that you are running on a supported operating system. A list of supported systems can be found on the Supported Platforms page.
- Check that the license server is available (try connecting to it). If it is available, check that the process lmgrd is running. If it is not running, restart it. Instructions for starting the license server daemon are given in Article 1899. If the daemon is running, check that the ports used by the license server are opened in the server's firewall. Then check the dates in your license file to ensure that the license is still valid. Usually you will receive an error message relating to the license if you have a licensing problem.
- Check whether the system configuration has changed. If it has, the current configuration might not compatible with Maestro or might be lacking some of the requirements for Maestro. Check with your system administrator for any changes, including reboots. You might have to reset some settings that were made temporarily and not included in the boot configuration, for example, or reinstall some libraries. You might also have to reinstall the graphics driver if the kernel was updated.
- On Windows, startup problems may be due to corrupt configuration files. To fix the problem, open a Windows Explorer window and go to the folder %APPDATA%\Schrodinger. Find the folder inside this folder with the same suite name as your release (for example, 2014-3) and rename it (for example to 2014-3.orig). Then try restarting Maestro. If Maestro starts, you can delete the renamed folder (2014-3.orig).
- If you are running 32-bit software on a 64-bit Linux machine, check that the 32-bit libraries are installed, in particular the X libraries, and the LDAP libraries (if using LDAP).
