This type of behavior is almost always due to your graphics card and/or graphics drivers.  EVS requires high level OpenGL support, and it hits the graphics card during initialization.

If the software was working previously, you might want to Roll-Back your graphics driver.  Otherwise, the first thing to try is to upgrade your graphics drivers.  If drivers do not solve the problem, your computer may not be able to run the software.

There is a strong link between the quality of graphics drivers and Operating Systems.

If you’re running Windows 7, which is an obsolete OS, the support for modern graphics cards is very poor.  If this is a newer laptop (my guess) and is running Windows 7, upgrading the OS, will likely resolve the problem.  We recommend Windows 10.
