I just bought Vegas Pro 23 after using Movie Studio for more than 20 years. The paid version shows 2 error messages on startup, both complaining about lack of OpenGL. I'm running Windows 10 and have no GPU. Vegas runs fine after these complaints, so it's clear that I don't need OpenGL. But it's annoying... When I click on "check for updates" I get the same error, plus an "updater failed" message. So I can't check for updates. (And why would an update check require OpenGL?) The test program did NOT show this behavior. Oh, and GPU acceleration is Off in preferences.
