i am having this problem it was another problem but i fixed it by turnin on framework so i am running windows 10 and i am hoping for someone to help me it isn't like the other errors when rendering my error is on start up
That error message says nothing. I don’t see how anyone can help you, especially when you’re being completely vague as to when it happens. What do you mean by when you start up? Does the message pop up the moment you start up? Or is Vegas displaying some information about where in the startup process it is before it happens? If so, what does it say?
First try repairing .NET Framework as described in section 13 of this post. If that doesn't work then work through the steps in this post, in particular the clean uninstall and reinstall described in section 14. Last resort would be a reinstall of Windows, as worked for the 2nd of those previous cases.
