It appears that the HLE doesn't allow you to access this "Mastercam Launcher 2020" program to turn off the hardware acceleration. Maybe this is only accessible in the premium version? So unless there's some other way to access this window it seems like Mastercam 2020 HLE is unusable without a dedicated GPU. Meaning laptops like my Surface Pro cannot use it. If someone using 2020 HLE has been able to access the Launcher window to turn this setting off please explain how. Thanks.
