I don't know, but it happened to Vegas pro 14 too, i tried reinstalling it, didn't work, i updated directx, didn't work either, tried reopening it and closing it a few times, it works once or twice but then it keeps corrupting, I don't know what's the issue but it has something to do with the system dll files :(
You tried updating graphics drivers?
Was it a Nahimic conflict that requires disabling windows presentation foundation in internal preferences?
I tried, but I can't find any other drivers compatible with my OS.
What is your OS and GPU?
Did you go into internal preferences (hold down shift and go to the preferences menu).
Windows 7 Home Premium, unknown, Haven't tried that out, I'll try and see what's the problem
Your GPU and driver version are unknown? Try device manager in Windows.
Anyway it may well be Nahimic- search this forum for details if you want to read about it.
[Intel(R) HD Graphics] if it's something else well I cant find it-
Alright.
Do you know the CPU? That will tell us which GPU it is. I have a HD630 working fine here on a 7th generation Intel CPU.
Has VEGAS ever worked on this system?
What build of VEGAS Pro 18 are you using?
