The Unable to initialize OpenGL error usually means that the OpenGL version on your system (driver) is not in line with a specific games system requirements or your system (driver) does not support OpenGL.
Typically when you see this message, you will need OpenGL 2.1 or higher and for some games (like with Delicious - Emily's Road Trip (D15), you will need 3.2.1 or higher.
Determine your OpenGL version:
1. Download the free program OpenGL Extensions Viewer through this link. (Choose the left download option, not the ES version).
2. After following the prompts to allow the program to install, the program will open in a new window. Allow a minute or so for the information to be gathered.
3. Click on Summary from the left side of the window, then you will see the OpenGL Version displayed.
Note: If the version is lower than 2.1 (or 3.2.1 for D15), then you likely won't be able to play the game on your system, however we recommend updating your graphic card driver as this may resolve the problem if your driver can support it.
