This may seem like a seriously complex problem, but surprisingly it isn’t,
So the system restores and constant re-installs are totally not necessary.
It is something as simple as a driver, a codec, a software or plugin you have that is
conflicting with Vegas, and so crashes it at startup.
So whatever you installed are automatically updated a month ago when the
problem occurred, you have done it again this time. The problem for me is that
i do not know what you have on your system (by the way quicktime has nothing
to do with it)…. So the most common one is, do you have Windows automatic
update enabled? if so, and you see it recently updated, then uninstall that
update and see…. Or have you installed anything at all on your system
recently?
