The most common cause of this problem is an outdated or missing video card driver. Twin and Explore require OpenGL 2.0 support from the video card to be displayed. If you want to use it on your own machine check if your video card supports this and if it does upgrade the driver and restart the application. If you are using Twin or Explore via Remote Desktop or X please note that these don’t forward the OpenGL support so while you can technically startup the application remotely – you will not be able to see it. To work around this – startup the application locally on the machine and then you can access and use it via Remote Desktop or X.

Another potential problem is when the application has been installed using a user account with administrator access and now you are trying to use it with a user account that does not have this privilege. Full access needs to be granted to the application folders which have been defined during installation – database folder, installation folder, and temp folder.

BitLocker on Windows can also prevent the application from running as it detects and prevents executables from running within a user profile. Configure BitLocker to allow this and the application will start up.

Since Twin 4.1.0, a running MySQL server is also required, without the MySQL server the Software can not start.
