![]() ![]() ![]() Note that when you ran the SETX command in step 2, it added the QT_OPENGL value to your environment. Setting the QT_OPENGL environment variable to “software” is the way to do that.Īnd with the change to use software instead of hardware, Qt, OpenGL and Dropbox all start properly. That failure causes Dropbox to throw up the “Failed to create OpenGL context for format QSurfaceFormat” error, which suggests that there is a problem with the computer’s graphics card/hardware.įortunately there is a way to instruct Qt: “Instead of using the computer’s graphics hardware for OpenGL, use software libraries”. So when you run Dropbox, both Qt and OpenGL will be started.īut for some unknown reason, when Dropbox is started as a Windows Service in Session 0, Qt and OpenGL fail to initialize. In turn, Qt requires OpenGL - a cross-platform API for rendering 2D and 3D vector graphics. The explanation is a bit technical, but here goes…ĭropbox uses Qt - a popular cross-platform development framework. Huge thanks go to Dropbox forum user Wilson7777, who alerted the community of this remedy. The OpenGL prompt should be gone - a relic of an unpleasant past. This forum post contains more discussion on the topic.Afterwards, restart Dropbox as a service. In any event, if all else fails and you are stuck using a Windows computer that is incompatible with Synthesia 10.3 or later, the previous release should continue to work: OpenGL 2.0 emulation libraries for Windows article 1369, updated 589 days ago Some applications will crash or fail to run, asking for OpenGL emulation libraries, sometimes ANGLE libraries. This is a rather unfortunate situation and a fairly good reason not to attempt using the latest operating system on a very old machine. So, even though the hardware may support the OpenGL standard that Synthesia requires, Windows 10 doesn't know how to utilize it. you are stuck with the generic Microsoft driver. Because Intel doesn't provide updated drivers but Windows 10 requires an updated driver. This is troubling because Windows 10 requires new drivers made specifically for Windows 10. So, 10 year old systems haven't had any driver updates since the release of Windows 10. ![]() There is a special situation worth mentioning where upgrading to Windows 10 actually limits your graphics capabilities: Intel routinely stops supporting hardware after a certain number of years. Intel's driver page has a utility that can find the latest drivers for your system. This seems to be most common on systems with integrated Intel graphics. We've heard from users running the generic Microsoft graphics driver instead of the "real" driver for their hardware. If you receive an error about this while launching Synthesia, there is still a chance your hardware is actually compatible. We've described the reasons in more detail here, but the short answer is that despite our best efforts to maintain compatibility for as many users on older hardware for as long as possible, it becomes more challenging as that hardware grows beyond 10 years old. ANGLE: This library converts OpenGL ES 2.0 API calls to DirectX 11 or DirectX 9 calls (depending on availability), removing the need to install graphics drivers. Starting with the 10.3 update, Synthesia now requires graphics hardware that is capable of OpenGL 2.0, which became a standard in 2004 (and was widely supported by 2007). The development platform for our class is a Microsoft Visual Studio 2010. Try to find an updated graphics driver for your computer. Installing OpenGL and Running OpenGL Programs on.
