There isn’t any Sony Vegas file anymore in my Computer , that’s the wierd thing. I have removed them all with revounistaller.
Also when i tried to install the Sony Vegas again i tried to do that on my primary SSD (C:) and not to my externals , i didnt know that windows has a problem with registry when you install programs there , cause so far no other programs had that kind of behavior.
I guess the only solution in the end might be a Windows re-format,if you consider that it will take only about less than an hour to make it , that is less than the 1+ week im trying to solve this problem 😛
